Algebra

Combining like termsStandard Form: ax² + bx + c = 0

Step-by-step explanation:

Step 1: Define

f(x) = 3x² - 2

g(x) = 2x + 4

(f - g)(x) is f(x) - g(x)

Step 2: Find

Substitute:                    (f - g)(x) = 3x² - 2 - (2x + 4)Distribute -1:                 (f - g)(x) = 3x² - 2 - 2x - 4Combine like terms:    (f - g)(x) = 3x² - 2x - 6

32

step-by-step explanation:

these are your clues: 1. kim ran 18 races2. this was four fewer races than twice thenumber, notice it says twice the number, so you would do the equation 18x2-4; which equals the number 32.thus, 32 is your answer.
