the answer is this because,

15 inches is 3 inches times by 5

Answer:

10 in

Explanation:

Old proportions:

2 x 3

New proportions

h x 15

Assuming the painting has been increased by a constant scale factor.

Where x is the unknown scale factor, and h is the height after it has been enlarged.


3 * x = 15\\2 * x = h

Rearrange second equation:


3 * x = 15\\x =(h)/(2)

Substitute:


3*(h)/(2) =15\\(h)/(2)=5\\h=10
