1) Which expression is equivalent to \( 2(r+6) \) ?

You can simplify the expression \( 2(r+6) \) by distributing the 2 to both terms inside the parentheses. This gives you \( 2r + 12 \). So, the expression equivalent to \( 2(r+6) \) is \( 2r + 12 \). To make sure your algebra is spot-on, always double-check each step! A common mistake is to forget to distribute to both terms, which would lead to incorrect answers. Just remember: distribute like you’re sharing delicious cupcakes with your friends!
