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 ar
ea of the original rectangle. How did the rectangle change?
3 was added to each side.
5 was added to each side.

The answer <span>5 was added to each side.
</span>
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, <span>5 was added to each side.</span>
Answer:
Sad how the verified answer is the wrong one.. The correct anser would be B) 6 was added to each side.

Answer:
F: 18
Step-by-step explanation:
find total amount of points
43 + 7 = 50
subtract half of 50 to find the midpoint
43 - 25
18
L = 18
f(8) = 6 (1-8) +11
= 6 (-7) + 11
= -42 +11
= -31
