Which polynomial expression represents the area of the outermost square tile, shown below?
a. x2+6x − 6
b. x2 − 9x + 6
c. x2 + 6x − 9
d. x2 − 6x + 9

Hence, option: D is correct.

The area of square tile is:

Step-by-step explanation:

Clearly from the figure we could see that the side of the square tile is given to be:

x-3.

As we know that the area of a square with side length 's' is given to be:

Area=s^2

Hence, the area of this square tile is given by:

Hence, the area of square tile with side length is given by:

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.
