To complete the square you take the coefficient of the 'b' term (10), divide it by 2 (10/2), then square it (5^2 = 25). This is the number you add.

Answer:
x = 12
Step-by-step explanation:
we can put this is a proportion: (new side 1) / (old side 1) = (new side 2) / (old side 2)
so in this case, 18 would be old side 1, x would be new side 1
12 would be old side 2, and 8 would be new side 2
plug these in: x/18 = 8/12
cross multiply 18 and 8: x = 144/12
now simplify: x = 12
