25 points. i am really trying to get this test done before midnight so i can get some sleep.

8s^3 - 9s + 3

Step-by-step explanation:

(7s^3 - 3s + 3) + (s^3 - 6s)

7s^3 - 3s + 3 + s^3 - 6s

8s^3 - 9s + 3

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
