Lerok [7]

Answer:

A) 2(9x - 2)

Step-by-step explanation:

The greatest common factor of 18x and -4 is 2.

B is wrong because 18 is not the greatest common factor of both, since 4 cannot be divided by 18 and result in a whole number.

C is wrong because 18x cannot be divided by 4 to produce a whole number.

D is wrong because it restates the problem in a different way, therefore not factoring it completely. 1 is a common factor of both, but not the greatest.

Basically, this problem is going to require you to solve for the area and multiply it with the given cost unit.

Area = Length*Height
Area = 100 ft * 8 ft = 800 ft²

Total Cost = (Unit Cost)(Area)
Total Cost = ($2/ft²)(800 ft²)
<em>Total Cost = $1,600</em>
