You simply multiply the expression on the outside (in this case, 3) by each of the expressions inside the parentheses, and add everything up. In this case, 3x + 3 times 4.

Sure thing, honey. To expand 3(x + 4), you distribute the 3 to both terms inside the parentheses. So, you get 3x + 12. That's all there is to it, darling.
