Answer 1

Answer: Choise A and Choise B.

Step-by-step explanation:

Given the following expression:

$3x+3(x+y)$

You can simplify it in order to find equivalent expressions.

Appying the Distributive Property, you get:

$3x+(3)(x)+(y)(3)=3x+3x+3y$

So:

1. If you add the like terms, you get this equivalent expression:

$3x+3x+3y=6x+3y$

2. But if you factor out 3, you get the following equivalent expression:

$3x+3x+3y=3(x+x+y)$

Therefore, the expression shown in Choice A and Choise B are equivalents to the expression $3x+3(x+y)$
