The answer is D. Because if it's 5x the width then make length 5x and width x so 12x because two lengths and two widths makes it 12x=96 divide and you get x=8 which means width is 8 cm

A = 2 a² + 2 a b
2 a² + 2 a b = 147/2
a² + a b = 36.75
a b = 36.75 - a²
b = ( 36.75 - a² ) / a
V = a² * b
V = a² * ( 36.75 - a² ) / a
V = 36.75 a - a³ ( maximum of the volume is when V` = 0 )
V` = 36.75 - 3 a²
36.75 - 3 a² = 0
3 a² = 36.75
a² = 36.75 : 3
a² = 12.25
a =√12.25
a = 3.5 ft
b = 24.5 / 3.5 = 7 ft.
Answer: The depth of the shelter for which the space inside is maximized is 3.5 ft.
Answer:
-x² + 5x
Step-by-step explanation:
Distribute -x to all terms within the parenthesis. Note that when multiplying a negative variable and a positive variable, the result is a negative variable. Also note that when multiplying a negative variable with a negative number, the result is a positive.
(-x)(x) = -x²
(-x)(-5) = 5x
-x² + 5x is your answer.
