Answer:
Let f(x) = Ax + B and g(x) = Cx + D where A, B, C, and D are non-zero constants. Use upper case letters for A, B, C, D and lower case letter for x in your answers below. (a) Find f(g(x)). f(g(x)) = A(Cx + D) + B (b) Find the slope of the function you found in part (a). slope = (c) Find the vertical intercept of the function you found in part (a). Do not write your answer as a point

Answer:
I'll setup the problem, then you can do the calculations
Step-by-step explanation:
Perimeter = 2width(W) + 2length (L)
Area = LW
L = 2.5 + 2W
LW = 62.5
substitute L in equation for area
![2.5W + {2W}^{2} = 62.5 \\ \\ {2W}^{2} + 2.5 - 62.5 \\ \\ use \: quadratic \: solution \\\frac{ - b ± \sqrt{ {b}^{2} - 4ac}}{2a}](https://tex.z-dn.net/?f=2.5W%20%2B%20%20%7B2W%7D%5E%7B2%7D%20%20%3D%2062.5%20%5C%5C%20%20%5C%5C%20%20%7B2W%7D%5E%7B2%7D%20%20%2B%202.5%20-%2062.5%20%5C%5C%20%20%5C%5C%20%20use%20%5C%3A%20%20quadratic%20%5C%3A%20%20solution%20%5C%5C%5Cfrac%7B%20-%20b%20%C2%B1%20%20%5Csqrt%7B%20%7Bb%7D%5E%7B2%7D%20%20-%204ac%7D%7D%7B2a%7D%20)
a = 2; b = 2.5; c = 62.5
