<span>2(3 - x) = -16
3 - x = -16/2
3 - x = -8
-x = -8 - 3
-x = - 11
x = 11</span>
I’m not really sure but I would have to guess 4.5 because all of the other numbers don’t have decimals
Answer:
(f · g)(x) = 3x³ + 6x² - 5x - 10
General Formulas and Concepts:
- Distributive Property
- FOIL (First, Outside, Inside, Last)
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x + 2
g(x) = 3x² - 5
<u>Step 2: Find (f · g)(x)</u>
- Set up: (x + 2)(3x² - 5)
- FOIL: 3x³ - 5x + 6x² - 10
- Combine like terms: 3x³ + 6x² - 5x - 10
