Asquare piece of fabric has an area of 16x^2+40x+25 square inches. the length of each side of the fabric is cx+d, where c and d are whole numbers. find an expression for the perimeter of the piece of fabric. then find the perimeter when x=2.

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.
