Question

How do you simplify the expression twice the sum of five times a number n and 60 ?

Answer 1

2(5n+60)

Explanation:

The Expression is:

Twice the sum of`color(white)(xxxxx` `=2[?+?]`

Five times `color(white)(xxxxxxxxx` `=2[5(?)+?]`

A number n `color(white)(xxxxxxxx` `=2[5n+?]`

And 60 `color(white)(xxxxxxxxxxx` `=2[5n+60]`

Thus the expression is `=2[5n+60]=10n+120`
