To compute the scale factor from D to C, look at one set of corresponding sides of D and C, the sides of length 7 and 35 inches, respectively. What would you have to multiply the 7 in side of D to get the 35 in side of C? The answer is 35/7 = 5. Thus 5 is the scale factor. This is verified by looking at the other corresponding sides of D and C, which are 9 and 45 and 5 and 25.
