Answer:
21
Step-by-step explanation:
Answer: 16
Step-by-step explanation:
We first find out the number of graphic novels that Kaley reads, we set the number as k.
3k = 30
k = 10
Then Kaley reads 6 graphic novels fewer than Safara, which means that we plus 6 to the number of graphic novels that Kaley read,
k + 6 = 10 + 6 =16

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 8x² + 5x - 2
x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-2) = 8(-2)² + 5(-2) - 2
- Exponents: f(-2) = 8(4) + 5(-2) - 2
- Multiply: f(-2) = 32 - 10 - 2
- Subtract: f(-2) = 22 - 2
- Subtract: f(-2) = 20
I know step 5 is (x-2)(x+2)(x+1)
But I don't know what step 4 is.
