Hey!
So perimeter = length + length + length + length
10+ 19 + 17 +11 = 57 inches
2x+5=47, solve algebraically to find x, the answer
A cross-section <span>is the intersection of a solid and a plane.

12x+30+4
12x+34
This is 12x + 34 because when we combine all like terms, we get it.
Your answer will turn out to be −4x^2+3x.
