Answer:
x^3-x^2+x-2+x^4
Step-by-step explanation:
Remove parenthesis.
3x^3-4x^2+x-7+x^4-2x^3+3x^2+5
Collect like terms.
(3x^3-2x^3)+(-4x^2+3x^2)+x+(-7+5)+x^4
Simplify.
x^3-x^2+x-2+x^4
This is the answe 0.602059991327962
You do not owe anything. In fact, they owe you $1.35 back in change.
To find this, first we have to find the cost of your gas. You can get this by multiplying the rate by the amount of gallons.
15.75gals * $2.39 = $37.65
As a result, we can see that the $39 would cover the entire cost with change.
