Answer 1

@Jaynator495 Please Help :3

Answer 2

Any ideas?

Answer 3

try dividing it by primes less than its closest sqrt

if no primes divide into it, then itself is prime

Answer 4

I think that it's Prime..

Answer 5

Idk.

Answer 6

29 is a small number, so test the primes less then say 7 to see if they divide into it

Answer 7

\[ 29\div?\]

Answer 8

2,3,5,7 .... its not even, or end in 5 or 0 .. so 3 or 7?

Answer 9

Uh, i'm very sorry but i'm confused

Answer 10

is it divisible by 3 or 7?

it is not even so it is not divisible by 2

it does not end in 5 or 0, so it is not divisible by 5

the only primes left to test that could divide into it are 3 and 7 at best

test them out

Answer 11

Ok.

Answer 12

A prime number, or prime, is an integer greater than one that has no integral factors other than itself and one.

Answer 13

um, so it's composite?

Answer 14

\[\sqrt{25}<\sqrt{29}<\sqrt{36}\]
\[5<\sqrt{29}<6\]
since sqrt(29) is no more than 6, then the primes less then 6 are needed to test

2,3,5, and 7 is just a better safe than not

is 29 divisible by 2,3,5, or 7?

Answer 15

is 29, divided by 2,3,5, or 7 result in an integer?

Answer 16

Yeah...

Answer 17

what is it divisible by?

Answer 18

i don't know! I'm having trouble with this subject.

Answer 19

A composite number has other integral factors than itself and one.

It can be composed of other factors :-)

Answer 20

well, i cant divide it for you ... there are 3 or 4 possible tests to run if you must.

Answer 21

This is another way of saying that prime numbers can only be evenly divisible by 1 and them self.

Answer 22

The answer is B, 29 is prime because no integer greater than 1 and less than 29 will divide into it evenly without a remainder.

Answer 23

Yeah, i figured it out lol.

Answer 24

Good job :-)
