you split the problem into two separate problems and go from there.
so, (5x+15) and (xy+3y) then you take out the common factor in both
so, positive 5 out of (5x+15) and positive y out of (xy+3y)
you'll then have 5(x+3) and y(x+3)
The x=3 is similar in both problems so you can combine them to make one and combine the two factors you took out to make another problem.
So your final answer is (x+3)(5+y)
Answer:
One pound costs 1.26, two costs 1.47, three costs 1.68, and four costs 1.89. So we calculate how much it increases in each pound.
1.26 + 21 = 1.47
1.47 + 21 = 1.68
1.68 + 21 = 1.89
1.89 + 21 = 2.10
2.10 + 21 = 2.31
2.31 + 21 = 2.52
2.52 + 21 = 2.73
8 pounds cost: 2.73
So I pay $ 2.73 for 8 pounds.

216inches cubed is the answer
Scientific notation has to be greater then 1 and less then 10 and a decimal is less then one so we have to bring that decimal over 6 places to the right to get 6 x 10^-6
Answer: 6 x 10^-6
