the polygons are similar but not necessarily drawn to scale, find the value of x

bigger polygon has x-3, 8, and 16
smaller has 2.5, 2, 4

x−3/2.5=8/2=16/4

x−3/2.5=4=4
x−3/2.5=4
x - 3 = 4(2.5)
x - 3 = 10
x = 10 + 3
x = 13

I've givin up at this point...

X=13 because the polygons are similar in shape but have a size difference of x4. Since x-3 is the equation and x=13, it would equal 10. And the only thing that 2.5x4 equals is 10. So thirteen IS your answer.

ITS 13 YALL WELCOME LMAO

Damon, where did the six come from if the polygons have no six in the equation?

the answer is 13

x = 13, trust me bruh

WHAT IS THE ANSWER!!!!!!!

x−3/2.5=8/2=16/4

x−3/2.5=4=4
x−3/2.5=4
x - 3 = 4(2.5)
x - 3 = 10
x = 10 + 3
x = 13

For the people with these options:

A. 0.9
B. 10
C. 120
D. 160

The answer is B. 10
