Question

Fan for everyone who helps, medal for whoever helps the most! :)

1. What is the sum of the polynomials?
(m + n + 3) + (m + n + 4)

2. Which expression can be used to find the difference of the polynomials?
(10m – 6) – (7m – 4)

3. Which expression can be used to find the difference of the polynomials?
(4m – 5) – (6m – 7 + 2n)

Answer 1

1. 2m+2n+7

Answer 2

(m+n+3)+(m+n+4)

Remove the parentheses that are not needed from the expression.
m+n+3+m+n+4

Combine all similar terms in the polynomial m+n+3+m+n+4.
2m+2n+7

Hope this helps. :)

Answer 3

That is for the first one.

Answer 4

Thank you! :)

Answer 5

Do you have choices for question two? I'm trying to figure out what it is asking for exactly.

Answer 6

a. [10m + (–7m)] + [(–6) + 4]
b. (10m + 7m) + [(–6) + (–4)]
c. [(–10m) + (–7m)] + (6 + 4)
d. [10m + (–7m)] + [6 + (–4)]

Answer 7

Answer is:
a. [10m + (–7m)] + [(–6) + 4]

Could you post the choices for the last one too?

Answer 8

Yeah, sorry. Openstudy isn't working good for me. Hold on.

Answer 9

a. (4m-5)+(6m+7+2n)
b. (4m-5)+(-6m+7+2n)
c. (4m-5)+(-6m-7-2n)
d. (4m-5)+(-6m+7-2n)

Answer 10

Answer to the last question is:
d. (4m-5)+(-6m+7-2n)

Answer 11

Thank you.
