Answer: -3x^2 + x +5
Step-by-step explanation:
4x+5 + -3x^2 - 3x ----> -3x^2 + x +5
$85.20/6= $14.20/pair is the answer because unit price equals cost/pairs
G(x) = 2x² - 5x + 2 = 2x² - 4x - x + 2 = 2x · x - 2x · 2 - 1 · x - 1 · (-2)
= 2x(x - 2) -1(x - 2) = (x - 2)(2x - 1)
g(x) = 0 ⇔ (x - 2)(2x - 1) = 0 ⇔ x - 2 = 0 or 2x - 1 = 0
x = 2 or x = 0.5
10 will be your answer because 4 x 5 divided by 2 is 10
