Question

Add the following:

$7m,n,2m,3n$

Answer 1

Find the sum of the polynomial

Given: $7m,n,2m,3n$

After rearranging and collecting the like terms. we get this by using the distributive law.

$$\begin{gathered} =7m+2m+n+3n \\ =(7+2)m+(1+3)n \\ =9m+4n \end{gathered}$$

Hence, the sum of $7m,n,2m,3n$ is$9m+4n$.
