y = -4
Step-by-step explanation:
12y + 4 = 8y-12
Subtract 8y from each side
12y - 8y +4 = -12
4y +4 = -12
Subtract 4 from each side
4y +4-4 = -12 -4
4y = -16
Divide by 4
4y/4 = -16/4
y = -4

solve for "b", to see what the base is
what about the height? well, h = 4b
The answer is 20%
[(150 - 125) / 125] × 100% = 0.2 × 100% = 20%
hope that i have helped!
