A4 in. x5 in. picture is used to make a wall banner that is 48 in. x 60in. this is an example of a (an): a. expansion b. contraction c. translation d. diagram

For this case we have the following dimensions:
 (4) * (5)
 Applying a scale factor we have:
 (4k) * (5k)
 The value of k is given by:
 k = 48/4
 k = 12
 Or equivalently we have:
 k = 60/5
 k = 12
 Substituting values we have:
 (4 (12)) * (5 (12))
 From here, we obtain the dimensions of the wall banner:
 (48) * (60)
 
 A. Expansion

The length is 23 and y because you add them together

1. 5/82.95% is better than 7/8
