Example of which mathematical property is 3(x+2)as 3x+6 an example of

Explanation:

The distributive property is

We multiply the outer term 'a' by each term inside the parenthesis.

In the example of 3(x+2), we multiply the outer term 3 with each term inside the parenthesis.

That's how we go from 3(x+2) to 3x+6

Another way to think of it is to think of 3(x+2) as three copies of (x+2) being added. So,

(x+2)+(x+2)+(x+2) = (x+x+x) + (2+2+2) = 3x+6

The distribution rule is the shortcut of repeated addition like this.
