Tony wrote the equation x² + 5x + 126 = x² + 17x + 66 to show that the area of a changed rectangle is 126 m² greater than the area of the original rectangle. How did the rectangle change?

3 was added to each side.

5 was added to each side.

6 was added to each side.

11 was added to each side.

The answer 5 was added to each side.

x² + 5x + 126 = x² + 17x + 66
____
Subtract x² from both sides:
x² + 5x + 126 - x² = x² + 17x + 66 - x²
5x + 126 = 17x + 66

126 - 66 = 17x - 5x
60 = 12x
x = 60/12
x = 5

Thus, 5 was added to each side.
