help plss help me find the awnser

Answer:
3) D
5) C
3) 6m+5n-m --> 6(5)+5(3)-(5)
30+15-5 --> 45-5 --> 40
5) 4(x+4)+2
4x + 16 +2
4x +18
Answer:
3)
Given:
m = 5
n = 3
We plug in these values into our equation (6m + 5n - m);
6m + 5n - m
Now modified, would be:
6(5) + 5(3) - 5
30 + 15 - 5
45 - 5
= 40
5)
If we simplify this expression,
4(x + 4) + 2
We use the distributive property to multiply 4 to both x and 4 which are in the brackets.
Which will now be;
4x + 16 + 2
Now we combine like terms (our constants):
(16 + 2) = 18
So it would be, now:-
4x + 18, C is your answer.
