Question

What is the length of DE?

Answer 1

C. 6

Explanation:

`(ZY)/(FE) =(XY)/(DE)`

`(12)/(8) =(9)/(DE)`

`12DE=(9)(8)`

`DE=((9)(8))/(12) =(72)/(12) =6`

Hope this helps

Answer 2

The length of DE should be 6. Scale factor should be 1.5 since 12/8 = 1.5. Then you have to do 9/1.5 which should give you 6. To check you should do 6 x 1.5 which will give you 9.
