A) Expand and simplify (x + 4)(x - 7)​

X x X=x²

X x -7=-7x

4 x X=4x

4 x -7=-28

-7x + 4x=-3x

x² + -3x -28

hope that helped :)

Step-by-step explanation:

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.
