Area of a rectangle = length x width
The answer is <span>A –x^2 + 3x + 15
</span>
3x² + 6 – 2x + 5x – 4x²<span> + 9
Rearrange it:
</span>3x² + 6 – 2x + 5x – 4x² + 9
= 3x² - 4x² - 2x + 5x + 6 + 9
= -x² + 3x + 15
Create the equation:
250-13x
Plug in 4 for the equation and solve:
250-13(4)
250-52
198
The answer is C. 198
1/4x+7=12
Subtract 7 from both sides
1/4x=5
Divide by 1/4 or multiply by the reciprocal
X=5*4
x=20
