Answer:
<h2>A. x + 4</h2>
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
f(x) = 3x + 2, g(x) = 2x - 2.
Substitute:
(f - g)(x) = (3x + 2) - (2x - 2) = 3x + 2 - 2x - (-2) = 3x + 2 - 2x + 2
<em>combine like terms</em>
(f - g)(x) = (3x - 2x) + (2 + 2) = x + 4
I will use the binomial distrubion to find the probability.

A - selecting a red checker exactly 7 times in 10 selections
(4x)(-3x^8)(-7x^3)
4 (-3)(-7) = 84
x(-x^8)(-x^3) = x^(1 + 8 + 3) = x^12
Answer: 84x^12
