Answer:
x = 122
Step-by-step explanation:
2x^2 + 9x + 4 = 0
x^2 + 9/2*x + 2 = 0
x = - 9/4 +- √(81/16 - 32/16) = - 9/4 +- 7/4
x1 = - 1/2
x2 = - 4
The equation that could be used to find how many gallons Erin would need to drive 92 miles is 92 = 23g (option c)
<h3>How many gallons is needed to drive 92 miles?</h3>
The first step is to determine the gallons needed to drive 1 mile. To do this, divide the 6 gallons by 138 miles. Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.
Gallons needed for 1 mile = 6/138
In order to determine the gallons needed for 92 miles, multiply the ratio gotten in the previous step by 92
(6/138) x 92 = 4 gallons
The option that gives 4 gallons is : 92 = 23g
g = 92 / 32 = 4
