Question

Which two terms can be combined in this expression?

Answer 1

the second option given

Answer 2

Option (b) is correct.

we can combine 3.2m and
`-(m)/(5)`

Explanation:

Consider the given expression,
`6+3.2m+(2)/(5)n-(m)/(5)`

WE have to find the two terms can be combined in this expression.

We can combine those term which have same variable with same degree.

Here, since degree of each variable is 1 and contain two variables m and n.

So we can combine m terms together.

As ,
`6+3.2m+(2)/(5)n-(m)/(5)=6+(3.2-(1)/(5))m+(2)/(5)n`

Thus, we can combine 3.2m and
`-(m)/(5)`

Option (b) is correct.
