Combine like terms 4x3-5x2+4x2-7x3-2x+3x2

=-3 +2  -2x

Step by step explanation

the equation is

4 -7 -5 +4 +3 -2x

we just have to simplify the equation

for this we will add and subtract the numbers with same powers i.e we will ad powers of x raise to power 3 with another x raise to power three

and similarly for other powers

=-3 +2  -2x

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.
