Question

Melanie’s bedroom floor is rectangular in shape and has a width equal to 8x−6 and a length equal to 7x−3. What equation represents the area of the floor?

Select one or more:
a. A=56x2+66x+18

b. A=56x2+18x+18

c. A=56x2−66x+18

d. A=56x2−18x+18

Answer 1

C

Explanation:

Since the area of a rectangle is the width multiplied by the length, the area of this one would be:

`(8x-6)(7x-3)= \\\\56x^2-42x-24x+18=\\\\56x^2-66x+18`

Therefore, the correct answer is choice C. Hope this helps!
