Answer 1

The given statement is,

"three times the absolute value of the sum of a number and 6".

Let the unknown number be n.

So, the statement " sum of a number and 6 " can be expressed as,

`n+6`

The statement "the absolute value of the sum of a number and 6" can be expressed as,

`|n+6|`

Hence, the statement "three times the absolute value of the sum of a number and 6" can be expressed as,

`3|n+6|`
