The lengths of two sides of a triangle are shown below:

side 1: 3x2 - 2x - 1

side 2: 9x + 2x2 - 3

the perimeter of the triangle is 5x3 + 4x2 - x - 3.

part a: what is the total length of the two sides, 1 and 2, of the triangle? (4 points)

part b: what is the length of the third side of the triangle? (4 points)

part c: do the answers for part a and part b show that the polynomials are closed under addition and subtraction? justify your answer. (2 points)

i need a picture

step-by-step explanation:

yes

step-by-step explanation:

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.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
