True.Composite numbers are positive whole numbers that can be divided with no remainder by something other than 1 and themselves.Even numbers can be divided without remainder by 2, so any even number greater than 2 can be divided without remainder by at least three numbers: 1, 2, and the number itself. That makes the number composite.

No - although all positive even numbers other than 2 are composite, this does not mean that all composite numbers are even - the first odd composite number is 9, which is equal to 3 x 3.

Even composite numbers can, odd composite numbers can't.

Some. Any product of a set of odd numbers will be odd. To be even, a composite number must have at least one even factor. Therefore odd composite numbers must exist.

The composite numbers in that list are 22 and 36 - you know they are composite, because they are even numbers. The other numbers are odd and prime.

Two composite numbers may or may not be relatively prime, depending on their factors. Relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.

True.

It is false.

2 is prime

Not all composite numbers are even, but all even numbers except 2 are composite.

True.

No, 2 is prime.

Yes, it is.

false. it is always even

False because 2 is an even number which is also a prime number.
