Please help me or no my parents is going to kill me with argument

Hi there!

Question 1: Since they already did the first step for you, the reason why (-6)(-3) is a positive number is because a negative multiply by a negative equals a positive. Plus the (-6)(-3) comes out to be 18.

Question 2: The reason why his answer is incorrect is because he said (-3)(-5) = (-15) which is completely wrong, remember a negative multiplied by another negative must equal a positive. So the next step should be (15)(-2) which then equals to the correct -30.

answer: 12

step-by-step explanation:

because yes

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.
