A painter paints rooms in a house. The painter purchases 12 gallons of paint and uses 4 gallons on the first day of work. Which equation could be used to find how many gallons of paint are left, g?

g+4=12

g÷12=4

4×g=12

12+g=4

g+4=12

Step-by-step explanation:

Since the painter used 4 of the 12 gallons, the painter now has 8 gallons, so g=8.

The equation g+4=12 represents this because if we solve it by isolating g then we get that g=8.

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors
