Answer:

d. -3m-4n+14

Explanation:

( 11-2m)-(n+5)+(-m-3n+8)

11-2m -n-5 -m-3n+8

11-2m-n-5-m-3n+8

-2m-m

-3m-n-3n

-3m -4n +11+8-5

-3m-4n+14

another similar question:

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

Simplify R - [S + T].

m - 2n - 2

-m + 2n - 2

3m - 4n + 14

-3m - 4n + 14

answer: B. -m -2n -2

Answer:

The answer is=-3m-4n+14

Explanation:

Step-by-step explanation:

Step 1: Express terms in the form R-S+T

Where R=11-2m, S=n+5, T=-m-3n+8

Replace values for R, S and T in R-S+T= (11-2m)-(n+5)+(-m-3n+8)

Step 1: Collect all the like terms

Open the brackets

11-2m-n-5-m-3n+8

Like terms are similar variables, for example;

(-2m, -m) are all like terms since they have a common variable (m)

(-n, -3n) are also like terms since they have a common variable (n)

(11,-5,8) are constants

Step 2: Solve

-2m-m-n-3n+11+8-5=-3m-4n+14

The answer is -3m-4n+14
