Consider the two expressions (A and B): A: -x to the power of 2
B:(-x) to the power of 2
Evaluate each expression for x = 2. Compare and contrast your solutions for expressions A and B. Explain in the form of a paragraph the process necessary to evaluate each expression. Describe the effect the placement of the parentheses has on the final solution.

the correct is answer is a 9-sided polygon!

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
