Question

Find the sum of 5m + 3n + p, -5p + 3n, and 2n - m.

Answer 1

Answer:

The sum of the expression 5m + 3n + p, -5p + 3n, and 2n - m is 4m + 8n - 4p .

Step-by-step explanation:

As given the expression

5m + 3n + p, -5p + 3n, and 2n - m.

Now adding the above expression

= 5m + 3n + p - 5p + 3n + 2n - m

= 5m -m + 3n + 3n +2n -5p + p

= 4m + 8n - 4p

Therefore the sum of the expression 5m + 3n + p, -5p + 3n, and 2n - m is 4m + 8n - 4p .

Answer 2

5m + 3n + p
-5p + 3n
2n - m

Arrange them in like terms

          5m + 3n +  p
                + 3n  - 5p
add;    -m + 2n       
         4m + 8n - 4p    Choice No. 4.
