A) {3, 7, 9, 10, 12}

B) {15, 18, 20, 21, 23}

C) {17, 21, 24, 25, 31}



D) {23, 27, 29, 30, 36}


aslo please explain

Answer 1

The correct answer is A.

Explanation:

In order for a set to be a solution set, all of the numbers in the set must satisfy the equation. In this case, we are looking to satisfy the equation x < 14. So we must be able to tell that every number in the set is less than 14. In each of the sets (except for A), there is at least one number that is greater than 14. There are no numbers greater than 14 in A.
