Answer: -12 but could be wrong
Step-by-step explanation:
I don't know that format but I'm going to take a guess.
x^2 +2x - 8 -(2x+8) then plug in x=2
x^2 + 2x - 8 - 2x - 8
x^2 -16
= 2^2 - 16 = -12
Ok I’m im not sure you can ask someone else sorry
Answer:
The first option.
Because we're solving for the price of each gallon, x will represent the cost of each gallon. Since 8.4 is the total amount of gallons, multiply 8.4 and x to get $23.94. Solve for x by dividing 23.94 to get $2.85 per gallon. To check this, substitute 2.85 for x into the equation: 8.4 (2.85) = 23.94
