15me ! is this answer correct?

The answer is wrong. The real answer would be 1.25.

Step-by-step explanation:

You take the size of the first shape, 8, and multiply it by each scale factor, 0.8, 1.25, 2.0, and 18.0, to find which would equal 10.

In this case 8 x 0.8= 6.4, 8 x 1.25= 10, 8 x 2= 16, and 8 x 18= 144. Therefore making 1.25 the correct answer because 8 x 1.25= 10, which is the size of the second shape.
