+4-13m-12n
__________


A)4m + 3
B)4m – 24n + 3
C)30m – 5
D)30m – 24n – 5

Answer 1

B) 4m-24n+3..... We only hv to add like terms basing to their signs

Answer 2

The answer is the option B

`4m-24n+3`

Explanation:

we have

`17m-12n-1+4-13m-12n`

Group terms that contain the same variable

`(17m-13m)+(-12n-12n)+(-1+4)`

Combine like terms

`(4m)+(-24n)+(3)`

`4m-24n+3`
