All you need to do is 36 x 3, which would be 108. So, the answer is 108 feet.
Answer:
C x=6
Step-by-step explanation:
sqrt(x+3) = x-3
Square each side
(sqrt(x+3))^2 = (x-3)^2
x+3 = (x-3)^2
x+3 = (x-3)(x-3)
FOIL
x+3 = x^2 -3x-3x+9
Combine like terms
x+3 = x^2 -6x+9
Subtract x from each side
x-x+3 = x^2 -6x-x +9
3 = x^2 -7x +9
Subtract 3 from each side
3-3 = x^2 -7x +9-3
0 = x^2 -7x+6
Factor
0 = (x-6)(x-1)
Using the zero product property
x-6=0 x-1 =0
x=6 x=1
Since we squared we need to check for extraneous solutions
x=1
sqrt(1+3) = 1-3
sqrt(4) = -2
2=-2
False
Extraneous
x=6
sqrt(6+3) = 6-3
sqrt(9) = 3
3=3
True solutions
FORMULA FOR SURFACE AREA OF SPHERE = 4 pi r^2
<span>r = 6 " area = 4 pi X 6 X 6 = 144 pi " squared </span>
<span>r = 12 " </span>
<span>area = 4 X pi X 12 X 12 = 576 pi" squared </span>
<span>ANSWER Area will be 4 times the original</span>
D because 4,815÷3 hours equals 1,605 pounds per hour, divide that by 60 min to get 26.75 pounds per min
