The expression that is NOT equivalent to 3(x + 3) is B. (3 + x) • 3.

Here's why:

A. 3x + 9: This is equivalent to 3(x + 3) because when you distribute the 3 in the latter expression, you get 3x + 9.

B. (3 + x) • 3: This is NOT equivalent to 3(x + 3). When you distribute the 3 in this expression, you get 3x + 9, which is not the same as 3x + 9.

C. 3(x + 9): This is equivalent to 3(x + 3) because when you distribute the 3 in the latter expression, you get 3x + 9.

D. 3 • x + 3 • 3: This is equivalent to 3(x + 3) because when you distribute the 3 in the latter expression, you get 3x + 9.
