  1. 1
  2. 2
  3. 3
  4. 4

hintHint:

A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object. It is the ratio of new image to the old image.

The correct answer is: 2


    S c a l e space f a c t o r space equals space k equals fraction numerator stack C apostrophe D apostrophe with bar on top over denominator stack C D with bar on top end fraction equals 10 over 5 equals 2
