For this case we have the following expression:
[tex]3 (x + 6)[/tex]
We must apply distributive property, which by definition establishes that:
[tex]a (b + c) = ab + ac[/tex]
Then, applying the distributive property to the expression we have:
[tex]3 (x + 6) = 3x + 3 * 6 = 3x + 18[/tex]
So, [tex]3 (x + 6) = 3x + 18[/tex]
Answer:
[tex]3x + 18[/tex]
