4 (x+3) 

Let's put this into parts.

 (4 times) basically just means that you're multiplying 4 into something.

(The sum of x and 3) means that you're adding x and 3 together, because  (and) means add. 

(The sum) means the answer to that equation, so we would put x + 3 into parenthesis because we don't have the answer to x + 3 yet.

So, our answer would be: 4 (x+3)
