C = cost on individual hat, "18 = 3c" would be the equation to describe how much each hat costs. Each hat would cost $6 each.
-20n-14
-4x5n=-20n
-4x3.5=-14
And that cancels out the plus sign so it will be subtraction.
Is 172 the area or perimeter.
The answer is B.She subtracted the GCF from the second term in the expression instead of dividing.
