im doing the second exam with the word problems and im stuck on this

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

Side 1: 3x2 - 4x - 1
Side 2: 4x - x2 + 5

The perimeter of the triangle is 5x3 - 2x2 + 3x - 8.

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)

Answer 25

awesome. i got 10/10 on this 1

Answer 26

but my prob was a tad dif

Answer 27

what was different about it?

Answer 28

do u get how i got that?

Answer 29

did you put the expressions in order then add them up?

Answer 30

Part A
(3x^2−4x−1)+(−x^2+4x+5)
2x^2+4

Answer 31

yes, i forgot about the negative upfront though... my bad
its good to check ur work ;)

Answer 32

i just added the two sides

Answer 33

and under it is that the answer?
is there a negative infront of the 3 or infornt of the 2 or not

Answer 34

there is no negative in the answer

Answer 35

ok

Answer 36

-x^2+4x+3/x+4
when i added i got this?
it seems really long compared to your answer

Answer 37

lets start with the first term... how did u get -x^2 ?

Answer 38

Math in english section? 0.0

Answer 39

yes we established that @Kperales

Answer 40

ok first i took the parenthesis away and then combined all the like terms
the i rewrote 3x^-1 as 3/x
then i added 5 to -1 to get 4
then i got 3/x+4-x^2+4x
and then just put it in order to get what i put before

Answer 41

ok hold on

Answer 42

ok

Answer 43

3X^2 + -x^2 = 2x^2
-4x + 4x = 0
-1 + 5 = 4

2x^2+4

Answer 44

got it?

Answer 45

combine like terms first

Answer 46

ok wait let me read through this

Answer 47

ok so the final answer is just 2x^2+4

Answer 48

yes

Answer 49

ready for part B?

Answer 50

yess

Answer 51

Part B
\[(5x ^{3}-2x ^{2}+3x-8)-(2x ^{2}+4)\]

Answer 52

is that the answer?
so what did you do to get it?

Answer 53

no. that is the equation

Answer 54

ok

Answer 55

ok so once i solve that i should have the answer?

Answer 56

yes

Answer 57

5x^3-4x^2+3x-12

Answer 58

is that the answer to B
