Your paper is blurry, but a 3rd degree polynomial is a polynomial where the highest exponent is three. i.e x³+2x²+9x-6. So check for the polynomial with the highest exponent being 3, and you will get your answer! :)

1hr is 60 min so
60÷15=4
45miles×2hrs=90
45÷4=11.25
90+11.25=101.25 miles
101.25 miles÷ 25 miles per gallon= 4.05 gallons
4.05 gallons× $2.75 per gallon= $11.1375
$11.1375= $11.14
Alicia spends $11.14 on gas to get to work
-6g/5 that would be the answer . This is how i got it.
6f+9g=3g+f
5f+9g=3g
5f=-6g
