4x = 32 - 2x
Add -2x (or subtract 2x) from each side
2x = 32
Divide both sides by 2
x = 16
Answer:
x = 1, x = -1
Step-by-step explanation:
-4x² = -4
x² = 1
x = 
x = ±1
Answer:
368 square feet
Step-by-step explanation:
We know that the domain is actually the number of rolls

However she can only get up to 10 rolls. Therefore the answer is:
all integers from 1 to 10, inclusive
