Respuesta :

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.

Answer:

C. 6

Step-by-step explanation:

[tex]\frac{ZY}{FE} =\frac{XY}{DE}[/tex]

[tex]\frac{12}{8} =\frac{9}{DE}[/tex]

[tex]12DE=(9)(8)[/tex]

[tex]DE=\frac{(9)(8)}{12} =\frac{72}{12} =6[/tex]

Hope this helps
