The wording of the second function may be interpreted in several differente ways. These are some:
g(x) = (x^2 +2)(x-8)
g(x)=x^2 + 2(x-8)
g(x) x^2 +2x - 8
I will work with the last one, so my system of equation is:
f(x) = - x +2.5
g(x) = x^2 + 2x - 8
f(x) = g(x) ⇒ - x + 2.5 = x^2 + 2x - 8
x^2 + 3x - 8 - x - 2.5 = 0
x^2 + 3x - 10.5 = 0
Use the quadratic formula to solve for x:
x = [ - 3 +/- √(3^2) - 4(1)(-10.5) ]/2
x = - 5.07 and x = 2.07

Answer:
the answer is 4
Step-by-step explanation:
let x= length of the first piece.
second piece is 2x, right
third piece x+5, right
Total, in x-talk, is x + 2x + x+5 and that equals 21 feet, right.
Combine like terms: 4x + 5 = 21. Still with me?
So 4x = 16 (do you see why?)
So, what x must x be is 4
