Question

Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8.

Simplify R - S + T.

A.) m - 2n - 2
B.) -m + 2n - 2
C.) 3m - 4n + 14
D.) -3m - 4n + 14

Answer 1

D -3m-4n+14. Once you write out the equation, you have to combine all the like terms, also known as simplifiying

Answer 2

Option D is correct

-3m -4n +14

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
