Answer:
c
Step-by-step explanation:
Perimeter = 2L + 2W → 240 = 2L + 2W → 120 = L + W → 120-L = W
Area = L x W → Area = L(120-L) → Area = 120L - L²
Find the derivative: dA/dL = 120 -2L → 0 = 120 - 2L → L = 60
Area = 120L - L² = 120(60) - (60)² = 7200 - 3600 = 3600
The maximum area is 3600 yds²
-m+8 is the correct answer you are welcome
I assume you mean least. That would be 8.
5(3 - x) - 4(2 - 3x) > 2
15 - 5x - 8 + 12x > 2 <em>distributed 5 and 4 on the left side</em>
7 + 7x > 2 <em>added like terms (15 and -8) and (-5x and 12x)</em>
<u> -7 </u> <u>-7 </u>
7x > -5
