Hi
3 dinners at $9 each.
9 x 3
2 kids' meals at $4 each
9 x 3 + 4 x 2
4 desserts at $3 each
9 x 3 + 4 x 2 + 4 x 3
$10 dollar off coupon
9 x 3 + 4 x 2 + 4 x 3 - 10
Solve using PEMDAS
9 x 3 + 4 x 2 + 4 x 3 - 10 = ?
27 + 8 + 12 - 10 = ?
35 + 12 - 10 = ?
47 - 10 = ?
37
The answer is 37
Hope this helps! :)
Answer:
(f · g)(x) = 4x³ + x² - 20x - 5
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
- Combining Like Terms
- Expand by FOIL (First Outside Inside Last)
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 4x + 1
g(x) = x² - 5
(f · g)(x) is f(x)g(x)
<u>Step 2: Find (f · g)(x)</u>
- Substitute: (f · g)(x) = (4x + 1)(x² - 5)
- Expand [FOIL]: (f · g)(x) = 4x³ - 20x + x² - 5
- Combine like terms: (f · g)(x) = 4x³ + x² - 20x - 5
