Answer:
x^3 +8x^2 +13
Step-by-step explanation:
(6x^2 - 3 + 5x^3) - (4x^3 - 2x^2 - 16)
Distribute the minus sign
6x^2 - 3 + 5x^3 -4x^3 + 2x^2 + 16
Combine like terms
x^3 +8x^2 +13
Answer:
24 miles per gallon
Step-by-step explanation:
Step one:
given data
total distance covered= 480miles
The total amount of gallons used is = 20
The miles per gallon
= 480/20
=24 miles per gallon
Step two:
hence the equation that we used in solving the problem is stated as
miles per gallon= total distance/total gallon sused
Number 1 is Rio Grande and number 2 is St. Lawrence River
