Answer:
4x^3 - 3x^2 - 14x + 6 (this is the formula since we don't know x)
Step-by-step explanation:
[(4x-2) x (x^2 - 3)] - [(x+2) x (x)] = 4x^3 - 3x^2 - 14x + 6
$ 33.82
If Lou already had 6.1 gallons in the 15-gallon tank, then the amount of volume left to fill was;
15 – 6.1 = 8.9
Lou, therefore, spent the following amount to fill the gas tank;
8.9 * $3.80 = $ 33.82
