<u>Question #2</u>
21 Miles per gallon
Divide the number of gallons by the amount of gas to get miles per gallon.
252/12=21 miles per gallon
x= 1 ±√21/3
x= 2.52753
x= - 0.527525
-(-6) ±√-6² - 4 (3) (-4) / 2(3)
6±√36 -(-48) / 6
6±√84/6
6±2√21/6
6/6 ±2√21/6
1±√21/3
1+ √21/3 = 2.52753
1-√21/3= - 0.527525
