Answer:
[tex]-\frac{2m+14}{n-2}[/tex]
Step-by-step explanation:
Hey there!
In order to find the sum, you need to add the numerators together since the denominators are the same
2m+9-4m+5
simplify
-2m+14
Now that the numerators are added together, we can put it back with the denominator
-2m+14/n-2
So the sum of the two fractions are [tex]-\frac{2m+14}{n-2}[/tex]
