Answer:
8x + 13
Step-by-step explanation:
The perimeter is the sum of the 5 sides of the polygon, that is
perimeter = x + 5 + 3x + x + x + 5 + 2x + 3 ← collect like terms
perimeter = 8x + 13
There are 128 ounces in 1 gallon. 128 divided by 3 is 42.6 (the six repeats). so therefore you are adding 42.6 ounces of cleaning solution to 85.3 ounces of water
First you subtract 3 from both sides so it would be: -5h = 30
Second you divide -5 from both sides so it would be: h = -6
