10m+7n-14

Step-by-step explanation:

The answer is 10m + 7n - 14

Step-by-step explanation:

Q = 7m + 3n

R = 11 - 2m

S = n + 5

T = -m - 3n + 8

[Q - R] + [S - T] is

[ 7m + 3n - (11 - 2m) ] + [ n + 5 - ( - m - 3n+8)]

Solve the terms in the bracket first

That's

( 7m + 3n - 11 + 2m ) + ( n + 5 + m + 3n - 8)

( 9m + 3n - 11 ) + ( m + 4n - 3)

Remove the brackets

That's

9m + 3n - 11 + m + 4n - 3

Group like terms

9m + m + 3n + 4n - 11 - 3

The final answer is

10m + 7n - 14Hope this helps you

Step-by-step explanation:

Given : ,

,

, and

Now ,

[ ∵ (-)(+)=(-) and (-)(-)=(+)]

[Note : when -1 is outside the parenthesis it indicates that -1 should be multiplied with each of the terms present inside the parenthesis .]

[Combine like terms.]

[ ∵ (-)(+)=(-) and (-)(-)=(+)]

[Combine like terms.]

Now,

[combine like terms]

Hence,

10m - 7n - 14

Step-by-step explanation:

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

[Q - R] + [S - T].

= (7m + 3n - 11 + 2m) + (n + 5 + m + 3n - 8)

collect all the like terms

= 7m +2m +m +3n + n + 3n - 11 - 8 + 5

= 10m + 7n - 14

The third option 10m - 7n - 14 is right

10m + 7n - 14

Steps:

[7m + 3n -(11 - 2m)] + [n + 5 -(-m -3n + 8)]

7m + 3n -11 + 2m + n + 5 + m + 3n - 8

10m + 7n - 14

Steps:

[7m + 3n -(11 - 2m)] + [n + 5 -(-m -3n + 8)]

7m + 3n -11 + 2m + n + 5 + m + 3n - 8

10m + 7n - 14

(7m+3n-11-2m)+(n+)-3n+8)

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

6m+n+2

that's what i got, and i'm in high school. i'm sorry try asking your teacher in the morning.
