If those are exponents, then...
3x^3 + 11x^2 + 4x + 1
----------------------------- Cancel out the 11x^2 with the x^2
x^2 + x

3x^3 + 10x^2 + 3x +1
Answer:
x = 8 , y = 3
Step-by-step explanation:
3x + 2y = 30
3x - y = 21 -> y = 3x - 21
3x + 2 (3x - 21) = 30
3x + 6x - 42 = 30
3x + 6x = 30 + 42
9x = 72
x = 72/9 = 8
y = 3*8 - 21 = 24 - 21 = 3
∴ x = 8 & y = 3
8 x 12 = 96 sq ft
<span>4 x 8 = 32 sqft </span>
<span>96 / 32 = 3 panels </span>
<span>3 x 4 = 12 panels. I'm not sure which answer that would be. :-( If any, I would select C.) 6 panels. </span>
