Question

I've been stuck on this for the past hour. Can someone tell me how to solve it?

Answer 1

Scale factor: 2.5

Explanation:

Scale factor is the ratio between corresponding measurements. And a pre image is basically an (original image) while an image is the translated version of the original.

I'm not sure what the best way to explain my answer is, but you can either multiply or divide to find the answer.

4 x 2.5 = 10

8 x 2.5 = 20

10 x 2.5 = 25

5 x 2.5 = 12.5

10/4 = 2.5

20/8 = 2.5

25/10 = 2.5

12.5/5 = 2.5

Answer 2

Your welcome! I sometimes get stuck on problems like you too for hours until I get it.
