Question

Select the expression that are equivalent to 4 m + 8 m

Answer 1

Consider the given expression,

`4m+8m`

It is observed that both terms are alike, and like terms can be added or subtracted directly.

So, the expression is simplified as,

`4m+8m=(4+8)m=(12)m=12m`

Thus, the given expression gives 12m upon simplification. So this will be the equivalent expression.

Therefore, the third option is the correct choice.
