Answer:
√33
x = -5/2 ± ---------
2
Step-by-step explanation:
Through completing the square, we get:
x^2 + 5x + (5/2)^2 - (5/2)^2 - 2 = 0, or
(x + 5/2)^2 - 25/4 - 2 = 0.
This simplifies to
(x + 5/2)^2 = 33/4
Taking the square root of both sides yields:
x + 5/2 = ±√(33/4), which can be solved explicityl for x:
√33
x = -5/2 ± ---------

Answer:
37.5 Miles Per Gallon
Step-by-step explanation:
The Mileage of a car is the total number of miles driven divided by the total number of gallons (liters) of gas used.
For this problem, the units is miles per gallon
Allison can drive 450 miles with 12 gallons of gas. So
Total Miles Driver = 450 miles
Total Gas = 12 gallons
Hence, the mileage would be 450 divided by 12:
Mileage = 450/12 = 37.5 Miles Per Gallon
