-----------------
0.04m² - n²
(0.2m)² - n²
<span>(0.2m + n)(0.2m - n)</span>
-----------------
So 37 1/2
each can hold 2 1/2 oz
how many cups can he fill
37 1/2=75/2
2 1/2=5/2
x=number of cups
x times 5/2=75/2
5/2x=75/2
multiply both sides by 2
5x=75
divide both sides by 5
x=15
he can fill 15 cups
The answer would be f(x)= x+47
