For perimeter you add all of the sides but for area you multiply each side
There is only one solution in the given equation -y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0. In solving this problem, apply first PEMDAS (parenthesis, exponents,multiplication, division, addition, subtraction). Then equation will transform into -y2+5y-7y2-9y+15y2+4y=0. Combine terms with same power and achieve 7y2=0. Divide both sides with 7 and perform square root of zero. Since the root is zero, we have one solution of the given equation which is y=0.
Since there are 4 quarts in a gallon and we have 28 quarts we would have 7 gallons.
<u>The answer is 7. </u>
150 x 12 = 1800
55 x 12 = 660
1800 + 660 + 45000 = 47,460
