Answer 2

Jake and Liu

Explanation:

We are given that an algebra class teacher asked for example of non prime numbers.

Jake says=51

51 have factors 1,3,17 and 51.

Teresa says=41

41 have factors 1 and 41.

Liu says=21

21 have factors 1,3,7 and 21.

We know that prime number are those numbers which have only two factors 1 and itself.

Composite number:It is that number which have more than two factors 1 and itself.

Therefore, by definition of prime number Teresa is incorrect in their response and Jake and Liu are both correct .
