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