The expressions on both sides of the equal sign are examples of the product of two polynomials, and the goal is to simplify these products into the standard form of a single polynomial. To do this, we use the distributive property of multiplication over addition.
Starting with the first expression (5x-3)(8x-4). We use the distributive property to expand the product of two polynomials into a single polynomial:
(5x-3)(8x-4) =
= (5x × 8x) + (5x × -4) + (8x × -3) + (- 4 × -3) =
= 40x² - 20x - 24x + 12 =
= 40x² - 44x + 12 =
= 10x² - 11x + 3.
In a similar manner, the second expression can be expanded and simplified. We use the distributive property to expand the product of two polynomials into a single polynomial:
(2x+8)(7x+6) =
= (2x × 7x) + (2x × 6) + (8 × 7x) + (8 × 6) =
= 14x² + 12x + 56x + 48 =
= 14x² + 68x + 48 =
= 7x² + 38x +24x.
So both expressions have been simplified into the standard form of a single polynomial, and both are equal to the expressions on the right side of the equal sign.

find the sum of the first 100 terms of the arithmetic sequence is 15250 while the sum of the next 100 terms is 45250. find the sum of the next 100 terms
The sum of the next 100 terms is 65250.
An arithmetic sequence is a sequence of numbers such that the difference between any two consecutive terms is constant. If we let "a" be the first term of the sequence and "d" be a common difference, then the nth term of the sequence is given by a + (n-1)d.
Since the sum of the first 100 terms is 15250 and the sum of the next 100 terms is 45250, we can write two equations to represent these sums:
100/2 * (2a + 99d) = 15250100/2 * (2a + 199d) = 45250We can use these equations to find the value of "d". Once we have found the value of "d", we can use the equation for the nth term to find the sum of the next 100 terms.
Subtracting the first equation from the second, we get:
100/2 * (100d) = 30000Dividing both sides by 100/2, we get:
d = 300Finally, using the equation for the nth term and n = 201, we get:
a + (200)d = a + 200*300 = 60000So, the sum of the next 100 terms is 65250.

Find δrh for this reaction as written. (use 1.0 gml−1 for the density of the solution and 4.184 jg−1∘c−1 as the specific heat capacity.)
To find ΔHrxn for Zn(s) + HCl(aq) heat, we use q = cmΔT and track down q = - 582.4 J, it is exothermic to show the response. ΔHrxn is equivalent to - 582.4 J, meaning the response discharges heat.
We can involve the condition for the adjustment of intensity energy, q = cmΔT, to ascertain ΔHrxn for this response.
q = heat energy change = cmΔT
where c = explicit intensity limit of the arrangement = 4.18 J/g⋅∘C
m = mass of the arrangement = thickness of the arrangement x volume = 1.0 g/mL x 50.0 mL = 50.0 g
ΔT = change in temperature = 24.3 ∘C - 21.5 ∘C = 2.8 ∘C
In this way, q = (4.18 J/g⋅∘C)(50.0 g)(2.8 ∘C) = 582.4 J
Since the response is exothermic (the arrangement discharges heat), the ΔHrxn will be negative, meaning the response discharges heat.
ΔHrxn = - q = - 582.4 J
Subsequently, the ΔHrxn of Zn(s) with HCl(aq) is - 582.4 J.
To find ΔHrxn, the intensity energy change, for the response of Zn(s) with HCl(aq), we utilize the condition q = cmΔT. The particular intensity limit of the arrangement is 4.18 J/g⋅∘C, the mass of the arrangement is 50.0 g, and the adjustment of temperature is 2.8 ∘C. In this way, q = - 582.4 J, meaning the response discharges heat, and ΔHrxn = - 582.4 J. This computation shows that the response of Zn(s) and HCl(aq) discharges heat, making it exothermic.

an office building worth $6 million when completed in 1997 was depreciated linearly over 50 years; that is, the book value of the building decreases at a constant rate, so that at the end of 50 years the book value is zero. a) what was the book value, in dollars, of the building in 2014?. answer: b) what will be the book value, in dollars, in 2028? answer:
The book value of the building in 2014 was $3.96 million. The book value of the building in 2028 will be $2.28 million.
a) The book value of the building in 2014 can be calculated as follows:
Book Value = Original Cost - (Depreciation Rate * Years Depreciated)
Depreciation Rate = Original Cost / Number of Years
Depreciation Rate = 6 million / 50 years = $120,000 per year
Years Depreciated = 2014 - 1997 = 17 years
Book Value = 6 million - (120,000 * 17) = 6 million - 2.04 million = $3.96 million
So, the book value of the building in 2014 was $3.96 million.
b) The book value of the building in 2028 can be calculated in a similar manner:
Years Depreciated = 2028 - 1997 = 31 years
Book Value = 6 million - (120,000 * 31) = 6 million - 3.72 million = $2.28 million.
So, the book value of the building in 2028 will be $2.28 million.

2-5x=2x-2+3x is this equation a 1 solution a no solution or in infinite solution
The linear equation has only one solution, and it is x = 2/5.
How many solutions does the linear equation has?Here we want to see how many solutions does the linear equation have.
The equation is:
2 - 5x = 2x - 2 + 3x
To check that, let's try to solve the equation.
We can simplify the right side to get:
2 - 5x = (2x + 3x) - 2
2 - 5x = 5x - 2
Nowwe canadd 5x in both sides to get:
2 - 5x + 5x = 5x -2 + 5x
2 = 10x - 2
Now add 2 in both sides:
2 + 2= 10x - 2 + 2
4 = 10x
4/10 = x
2/5 = x

if the mean of the nails is 8.9 and the standard deviation is 5.56 what is the probability that a bag of 225 nails would be more than 2100?
The probability of getting a z-score greater than 0.15 is approximately 0.5693.
The probability of getting more than 2100 nails in a bag is approximately 0.5693.
The number of nails in a bag is a discrete random variable, so it's not appropriate to use a normal distribution to model it.
Also, the mean of 8.9 and standard deviation of 5.56 are for a single nail, not for a bag of 225 nails.
To answer the question, we need more information on the distribution of the number of nails in a bag.
Assuming that the distribution is approximately normal, the mean of the number of nails in a bag would be 225 * 8.9 = 2009 and the standard deviation would be the square root of 225 * (5.56)^2 = 59.11.
With these values, we can use a standard normal distribution to find the probability of getting more than 2100 nails in a bag:
z = (2100 - 2009) / 59.11 = 0.15
Note: This calculation assumes that the distribution is approximately normal, and that the mean and standard deviation of a single nail are accurate. These assumptions might not hold in practice, so the answer should be taken with caution.

given a standardized normal distribution, between what two values of z (symmetrically distributed around the mean) will 68.26 percent of all possible z values be contained?
68.26% of all possible z values are contained between -1 and 1.
The formula for the 68-95-99.7 rule states that 68% of the data should fall within 1 standard deviation of the mean, 95% of the data should fall within 2 standard deviations of the mean, and 99.7% of the data should fall within 3 standard deviations of the mean. Therefore, for a standardized normal distribution, 68.26% of all possible z values are contained between -1 and 1.
To calculate this, first recall that for a normal distribution, the mean is 0 and the standard deviation is 1. Then use the 68-95-99.7 rule to determine that 68% of the data should be contained within 1 standard of the mean. Since the mean is 0, this means that 68% of the data should be contained between -1 and 1. Therefore, 68.26% of all possible z values are contained between -1 and 1.

in hypothetical measurements, you record 1 decimal when using a graduated cylinder, 2 decimals when using a buret, and 4 decimals when using a balance. which device is most precise in measuring volume? why?
The graduated cylinder is most precise in measuring volume.
Precision is the degree to which separate measurements agree with one another. The general rule is that you can estimate one additional digit past the measuring device's smallest division, 100-mL graduated cylinders are read to 1 decimal, and the smallest graduated cylinder will hold the entire volume.
Precision refers to the number of significant figures in a measurement. When measuring liquid volumes, it is critical to read the graduated scale from the lowest point on the curved surface of the liquid, known as the liquid meniscus.
Graduated cylinders are ideal for precise liquid measurements with a much smaller margin of error.The device with the most precision in measuring volume is the balance. Precision refers to the level of detail and the number of significant digits in a measurement, and more significant digits indicate a higher level of precision. In this case, the balance provides the greatest level of precision with 4 decimal places, while the graduated cylinder provides only 1 decimal place and the buret provides 2 decimal places.This means that the balance provides the most accurate and detailed measurement of volume compared to the other two devices.

what is the location of earths center relative to a great circle defined by a pair of widely spaced flagpoles on earths surface
The location of earths center relative to a great circle defined by a pair of widely spaced flagpoles on earths surface is:
directly beneath the great circle defined by the two flagpoles.
The great circle defined by two flagpoles on the Earth's surface is a line that bisects the sphere of the Earth into two equal parts. This line passes directly through the center of the Earth, so the center of the Earth is located directly beneath the great circle.
The Earth is a three-dimensional object, so if two points on its surface are connected with a line, that line must pass directly through the center of the Earth.
This line is called a great circle because it is the largest possible circle that can be drawn on the surface of the Earth. The great circle formed by two widely spaced flagpoles on the Earth's surface serves as a reference point for determining the exact location of the Earth's center relative to the surface.
