Which of the following is a composite number?
a. 29
b. 13
c. 91
d. 139

A composite number is a number that can be divided evenly by numbers excluding 1 and itself.

29 is a prime number because it is divisible by only one and itself, so A is not the correct answer.

29/29 = 1 | 29/1 =29

13 is a prime number because it is divisible by only one and itself, therefore, B is not the correct answer.

13/13=1 | 13/1=13

91 is a composite number because it is divisible by 1, 7, and 91.

Hope this helps! :)

I’m a smart person so that’s why i think it was 6

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
