Rectangular numbers are a subset of composite numbers. The squares of prime numbers will be composite but not rectangular.

composite numbers are those that have more than 2 factors. all even numbers other than 2 are composite numbers and some odd numbers are composite numbers. numbers that are prime are the numbers that are not composite numbers i hope this answers your question :)

No. Prime numbers cannot be composite and composite numbers cannot be prime!

All numbers have factors. Some factors are prime numbers, some are composite numbers. A factor that is a composite number is a composite factor.

There are not 10 laws of composite numbers so the question is based on a complete misunderstanding of what composite numbers are!

Both are composite numbers

The number of composite numbers is infinite.

A composite number is defined as a "positive integer with a positive divisor other than one and itself". So therefore, while negative numbers can have factors in the same way as positive numbers, none is considered prime.

there are more composite numbers the prime becuz more things can be divided into

Yes, the numbers from 90 to 96 are composite numbers.

There are many, many more composite numbers than prime numbers. For example, beyond the number 3, every other number is composite, as it is divisible by 2. Following this, every number ending with a 5 other than 5 itself is composite, as it is divisible by 5, and every third odd number is divisble by 3. There are many complicated divisibility tests for numbers above 5.

30,32,33,34,35,36,38,39,40 are the composite numbers between 30 and 40. Composite numbers are numbers that are not prime numbers.

849670 is a composite number. All even numbers over 2 are composite numbers.
