Answer:
40 ft^2
Step-by-step explanation:
lateral surface area -Slat = 24 ft^2
top surface area-Stop = 8 ft^2
bottom surface area -Sbot = 8 ft^2
24+8+8= 40
total surface area -Stot = 40 ft^2
I got 3.825
your equation would be
(2x-1)(x+7)=72
when you distribute youd get
2x^2 +13x -7 =72
move the 72 over giving you
2x^2 +13x -79=0
i used the quadratic formula and the answer would be 3.825 because a negative answer wouldn’t make sense in this situation
