Answer:

(g · h)(5) = -50

Step-by-step explanation:

Step 1: Define

h(x) = x - 7

g(x) = x²

Step 2: Find (g · h)(x)

(g · h)(x) = x²(x - 7)

(g · h)(x) = x³ - 7x²

Step 3: Find (g · h)(5)

(g · h)(5) = 5³ - 7(5)²

(g · h)(5) = 125 - 7(25)

(g · h)(5) = 125 - 175

(g · h)(5) = -50

Solve for x. 0=65892.56*x^(-1.67)

scoundrel [369]

$0=65892.56\cdot x^{-1.67}$

It would seem the only solution is 0, but $x^{-1.67}=\frac{1}{x^{1.67}}$ and the denominator of the fraction can't be equal zero, therefore there's no solution.
