-7(x-4) = 63. Divide each side by -7.
x - 4 = -9. Add 4 to each side.
x = -5
Since they are similar both dimensions would have the same ratio. The ratio of 5 and 15 is 3. 15 is 3 times larger than 5, so the unknown dimension is 3 times larger than the known dimension.
3 x 10 = 30
The unknown dimension is 30
