Answer:
Option D is correct
-3m -4n +14
Step-by-step explanation:
Given:
Q = 7m + 3n,
R = 11 - 2m,
S = n + 5, and
T = -m - 3n + 8.
We have to Simplify R-S+T
R -S +T = 11 - 2m - (n+5) + (-m -3n +8) = 11 - 2m-n-5-m-3n+8
Combine Like terms we have;
R -S +T = -3m -4n +14
Therefore, the Simplification of R -S +T is, -3m -4n +14
