A student made a mistake when rewriting the expression 4(5 + 𝑥) as 20 + 𝑥. What did they do incorrectly?

• The student should have found the sum of both 4 and 5, and 4 and x. The correct expression should be (4 + 5) + (4 + x), which simplifies to 13 + x.

• The student should have multiplied both terms inside the parentheses by 4. The correction expression should be 20 + 4x.

• The student should have found the sum of 4 and 5, and then x. The correct expression should be (4 + 5) + (x), which simplifies to 9 + x.

• The student should have found the product of 4, 5, and x. The correction expression should be 4(5)(x), or 20x.
