The length of DE is 10 units

Step-by-step explanation:

Find the length of DE using the distance formula.

(-4,2) (4,-4)

just did it.

First, find the distance AB by the formula:

If A(0,-7) and B(8,8), then

Dilating polygon ABCD by a scale factor of 2 with the center of dilation at the origin to create polygon A′B′C′D′, you increase the distance AB twice, A'B'=2AB. Thus, A'B'=2·17=34 units.

AB=17 units, A'B'=34 units.

d = √1156 units

Step-by-step explanation:

We have given end-points of AB.

(0,-7) and (8,8)

We have to find length of A⁰B⁰.

Scale factor is 2.

Hence, end-points of A⁰B⁰ are

2(0,-7) and 2(8,8)

(0,-14) and (16,16)

Hence, we can find length of A⁰B⁰ by using distance formula.

d = √(x₂-x₁)²+(y₂-y₁)²

Putting values ,we have

d = √(16-0)²+(16-(-14))²

d = √(16)²+(16+14)²

d = √256+900

d = √1156 units which is the answer.

D.

Step-by-step explanation:

Given: We can find the length of FG using the Distance Formula:

[Distance formula to find length of line from point to point is given by :-

]

Since, and

Therefore,

Hence, the formula also represents the length of FG is .

34

Step-by-step explanation:

The scale of factor is 2. Then, you must multiply the coordinates of the endpoints AB by 2 to obtain the coordinates od the enpoints A'B':

Substitute values into the formula, then you obtain that the length A'B' is:
