C. 5x² - 4
General Formulas and Concepts:
<u>Algebra I</u>
- Composite Functions
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 4x² + 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) = 4x² + 1 + x² - 5
- Combine like terms: (f + g)(x) = 5x² - 4
Let's turn this sentence into an equation:
8n = -n + 36
Then solve:
9n = 36 => n=4
The answer is 3 N=4 and P=3 N+P=7. No other two combinations will give you a rational number
Your answer is: 128 pi.
pi x 4^2 x 8
pi x r ^2 x h
