The answer is 76. 2(-3)=-6 -6(-6)=36. 5 times the absolute value of 8 is 40. 36+40=76
I do believe it would be 12 percent, if rounded.
Given:

In the given figure, PS=x, RS=35, UV=20, VW=25 and TW=15
To find:
The scale factor from PQRS to TUVW.
Solution:
We have,

We know that the corresponding sides of similar figures are proportional. The scale factor is the ratio of one side of image and corresponding side of preimage.
The scale factor is:



Therefore, the scale factor from PQRS to TUVW is
.
