What is the expression equivalent to 4(3 + x)?

Explanation:
Distribute the number outside the parentheses to each term inside. Multiply 4 by 3 and by x separately: 4 × 3 is 12, and 4 × x is 4x. Put them together to get 12 + 4x. This shows exactly how 4(3 + x) expands. The result is also the same as 4x + 12, just written in a different order. The other forms would miss the 12 or mix up the terms, so they don’t come from distributing 4 across both terms.
