Question

Simplify 5(m + 9) (explain as much as possible)​

Answer 1

`5m + 45`

Explanation:

When there's a number outside a bracket, in this case it's 5, without a operator (+, -, ×, ÷) means that it'll automatically multiply with each and every content inside the bracket.

So

`5 * m = 5m`

and

`5 * 9 = 45`

=

`5m + 45`

Hope this helped!
