The length of overline CD is 12 units. C^ prime D^ prime is the image of overline CD under a dilation with a scale factor of n. Which of these are true? Choose all that are correct.

A, D , and E

Step-by-step explanation:

We have that:

is the image of CD after a dilation of scale factor n.

We use the relation between the image length and object length:

Option A

If n=3/2, then

This is true.

Option B

If n=4, then

This is false.

Option C

If n=8, then

This too is false.

Option D

If n=2, then

This is true

Option E

If n=3/4, then

This is also true.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
