You want to have your carpet cleaned in your living room which measures 12’ by 14’. Company A charges $2.75 per square foot and company B charges $450 per room. Which company should you hire to get a better deal?

Company B

Step-by-step explanation:

First we must calculate the area of the carpet. Variable A represents area.

So the area of the carpet is 168 square feet.

To find what company A will charge we will multiply the 168 by 2.75 they charge per square foot.

Company A charges, $462, while Company B will charge $450 for the one room.

This means Company B has the better price.

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
