Answer 1

the image is smaller than the pre-image so the scale factor will be < 1
Given the measures 12 and 9 what do you the scale factor is?

Answer 2

BC=B'C'-3

Answer 3

it can be written as a fraction < 1 agreed?

Answer 4

I think the scale factor is 3 but i'm not sure... and agreed.

Answer 5

no - 3 would mean that the image's sides would be 3 times the sides of the pre-image.

Answer 6

12 * scale factor = 9
so scale factor = ?
