Quantity of paint left = 
Taking LCM for 5, 6, 8, we get LCM = 120
Hence, Mark will have gallons of paint left after painting the mural.
2+12a. When adding, you're only collecting "like terms".
ABC ~ A’B’C’
So, AB=A’B’ , BC=B’C’ , AC = A’C’
Given, AB=15 and A’C’=4
So, AC = 4 , A’B’ = 15
N = -5 sorry I only answered the second one
0^2/0^9 = 0/0, therefore your answer is 1/1 considering that it is a fraction that is 100%, but if you divide 0 by 0, according to Keith’s theory you should have an endless number aka Infinity.
