Silvio wants to find the perimeter of quadrilateral abcd. he begins by computing the length of side ab using the distance formula. finish silvio’s work to find the length of side ab. The perimeter of quadrilateral abcd is 20 units.

The total length of a shape's boundary is referred to in geometry as the perimeter of the shape. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.

A regular polygon's perimeter is equal to the product of all of its sides, which is equal to the number of sides times the length of a side.

We use the general method to get the perimeter of an irregular shape since the sides of an irregular polygon might not all be the same length.

Therefore, the irregular polygon's perimeter equals the total of its sides.

Answer:

There are no values of x that make this equation true.

Step-by-step explanation:

We know h(x)=[tex]\sqrt{x-3} +5[/tex]

So lets substitute h(x) for 3

3=[tex]\sqrt{x-3}+5[/tex]

We are going to then subtract 5 from each side leaving us with

-2=[tex]\sqrt{x-3}[/tex]

We then need to get rid of the square root, so we will square both sides. which gives us

4=x-3

We then need to subtract 3 from both sides which leaves us with

x=1

However, when you substitute 1 for x into the original equation, you get

h(x)=[tex]\sqrt{-2}+5[/tex]

Which is not equal to 3

Therefore, there are no values of x that make this equation true.

We get the surface area as 202 inches² and volume as 168 inches³.

The surface area of a cuboid is given by:

Surface area = 2xy + 2xz + 2yz

Here length = x = 7 inches

Breadth = y = 3 inches

Height = z = 8 inches.

Substituting the values in the formula, we get that:

Surface area = A = 2(7)(3) + 2(7)(8) + 2(3)(8) inches²

A = 42 + 112 + 48 inches²

A = 42 + 160 inches²

A = 202 inches²

Volume of a cuboid is given by :

Volume = xyz

Substituting the values, we get that:

Volume = (7) (3) (8) inches³

Volume = 21 × 8 inches³

Volume = 168 inches³.

Therefore, we get the surface area as 202 inches² and volume as 168 inches³.

The answer is 8 markers

Step-by-step explanation:

Since all children are collecting markers from Rachel who has 15 markers, the equation will be:

Markers Left = 15 - 4- 3

Markers Left = 11 - 3

Markers Left = 8

The difference between the two points ; (-3,10 )

given

(-4,-1)  and (1,-9)

here we have to find the difference between -4 and -1

which is -3 so u go -3 spaces left so it would be -3

then , find the difference between 1 and -9 which is 10 so u go 10 spaces down so the difference between is;

(-3,10).

therefore the distance between two point are (-3,10)

Distance between two points is the length of the line segment that connects the two given points. Distance between two points in coordinate geometry can be calculated by finding the length of the line segment joining the given coordinates.to know more about distance.

We will use the distance formula in order to find the distance between points a and b. By substituting the points A(3, 4) and B(1, 2) in the above formula we get our required distance d. Hence, distance d = 2√2 units

Answer:

11

Step-by-step explanation:

Plug 4 into the x, 6(4) = 24

24 - 13 = 11

The coordinates of the other endpoint U are found to be (Xu, Yu) = (10, 5).

The coordinates are a pair of numbers which characterize the exact location of a point on a cartesian plane through using horizontal and vertical lines.

Now, as per the question.

To find the coordinates of U, use the midpoint formula with the coordinates of points u and v (Xv, Yv) and (Xm, Ym) respectively.

Let's refer to them as (Xu, Yu)

Midpoint formula {(Xv + Xu)/2, (Yv + Yu)/2)}

Fill in the recognized coordinates as needed.

Point V at (10, 7) =  (Xv, Yv)

Midpoint, point M at (10, 6) = (Xm, Ym)

For the x coordinates;

(10 + Xu)/2 = 10

Xu = 10.

Similarly for the y coordinate;

(7 + Yu)/2 = 6

7 + Yu = 12

Yu = 5

We can test this by plugging U's coordinates into the midpoint formula.

(10 + 10)/2 = 20/2 = 10

(5 + 7)/2 = 12/2 = 6

Therefore, the coordinates of the are (Xu, Yu) = (10, 5).

Answer:

The number of years to the nearest hundredth is t = 21 years and 3 months.

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]

Where A = Final amount

          P = Principal amount

          r  = annual rate of interest

          n = how many times interest is compounded per year

          t = How long the money is deposited or borrowed (in years)

It is given that:

A = $25,600

P = $29,00

r = 10.4 = 0.104

n = 4

[tex]\rm 25600 = 2900(1+\dfrac{0.104}{4})^{4t}[/tex]

After solving:

t = 21.212 years

Or

t = 21 years and 3 months

Thus, the number of years to the nearest hundredth is t = 21 years and 3 months.

1) The solution to the given quadratic equation is; x = ¹/₂(3 ± 3√2)

2) The solution to the given quadratic equation is; x = 5/6 or -2

1)  (2x - 3)² = 18

To fid the value of x, we can solve by first taking the square root of both sides to get;

√(2x - 3)² = ±√18

Add 3 to both sides using addition property of equality to get;

2x - 3 = ±3√2

2x = 3 ± 3√2

x = ¹/₂(3 ± 3√2)

2) 2(5x + 2)² = 64

To fid the value of x, we can solve by first  dividing both sides to get;

(5x + 2)² = 32

Take square root of both sides to get;

(5x + 2) = ±8

Subtract 2 from both sides using subtraction property of equality to get;

The coordinates of the vertices of the triangle A'B'C' are (14, 3), (- 6, 2) and (- 8, 6), respectively. (Correct choices: A, E, D)

In this question we find the locations of the three vertices of the triangle, each of which has to be transformed by using a non-rigid transformation rule, that is, a transformation rule that does not conserve the original form of the triangle. We are asked to determine the possible coordinates associated with the triangle A'B'C.

If we know that A(x, y) = (7, 6), B(x, y) = (- 3, 5) and C(x, y) = (- 4, 9), then the coordinates of the vertices of the triangle A'B'C' are:

A'(x, y) = (2 · 7, 6 - 3)

A'(x, y) = (14, 3)

B'(x, y) = (2 · (- 3), 5 - 3)
