Answer:
Step-by-step explanation:
(13)2−(2x+7)=0
19x2−2x−7=0
9(19x2−2x−7)=9(0)
x2−18x−63=0
(x−21)(x+3)=0
Therefore, the value of x are
x - 21 = 0 and x + 3 = 0
x = 21 x = -3
Since 4 quarts equal 1 gallon, 2 gallons and 8 quarts. 1/2 of a gallon equals 2 quarts. When you add 8 and 2 you get 10 quarts. The answer is 10 quarts.
