x^2+8x-2=18
x^2+8x-2-18= 18-18
x^2+8x-20= 0
(x-2)(x+10)=0
x-2= 0 , x+10=0
x-2+2= 0+2, x+10-10= 0-10
x=2 , x=-10
Answers are x= 2 -B, x=-10 -A.
Answer:
The surface area is 22 square feet
Step-by-step explanation:
For a right rectangular prism, we have the formula for the area as;
A = 2(lb + lh + bh)
Accordingly, we have l as the length, b as the breadth and h as the height
Using the given dimensions, we have
A = 2(3(1) + 3(2) + 1(2))
A = 2(3 + 6 + 2)
A = 2(11) = 22 square feet
