What is a simpler form of the expression? Show all steps
-3(-4y+3)+7y

-3(-4y + 3) + 7y        Distribute -3 into (-4y + 3)

(-3)(-4y) + (-3)3 + 7y    (two negative signs cancel each other out and become positive)

12y - 9 + 7y    Combine like terms(terms that have the same variable and power/exponent), which are only 12y and 7y because the have the same variable of y and an exponent of 1

19y - 9         (this is as far as you can simplify)

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
