If two figures are similar, then the ratio of its corresponding sides is proportional

$\frac{YZ}{EF}=\frac{XY}{DE}$

substitute the given values

$\frac{YZ}{6}=\frac{15}{10}$

solve for YZ

$YZ=6(15)/10\\YZ=9\ cm$

-3(x + 9) = 15 Enter value for x

Crazy boy [7]

Answer:

x = -14

Step-by-step explanation:

-3(x + 9) = 15

Divide each side by -3.

-3(x + 9)/-3 = 15/-3
x + 9 = -5

Subtract 9 from each side.

x + 9 - 9 = -5 - 9
x = -14
