1. t^6 – 64

2. y² + 5y – 84

3.18x^4– 72x²

4.9p² - 54p + 72

5.(x^2 - x - 6)/(x^2 - 9)

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

answer: 2 and 1
