Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = x² + 1
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(a + 1) = (a + 1)² + 1
- Expand [FOIL]: f(a + 1) = a² + 2a + 1 + 1
- Combine like terms: f(a + 1) = a² + 2a + 2
The answer would be 24pi inches.
You can find this by using the formula for a circumference and plugging in the value of the radius.
C = 2pi*r
C = 2pi * 12
C = 24pi
Answer:
it will take 25 hours
Step-by-step explanation: add 10 and 15
3x and -2x are like terms because they both have the variable X
