Pleaseeeee help me!!!!!!!!!!!!!1
A. It is odd.
B. It has more than two factors.
C. All of its factors are prime numbers.
D. It is not divisible by any number except one and itself.
I PICKED b
Pleaseeeeee help i don't want to be late to brand practice!!
B is correct. You will find not all odd numbers will be prime...
i know i am annoying but pleaseeeeeeeeeeee helppppppppppppppp!!!!!!!
You're correct.
Composite number can be written as the product of two or more primes.
In this case:
25 = 5 ∙ 5
Answer C
You are correct! 25 is indeed a composite number because it has more than two factors. A composite number is any number greater than 1 that can be divided evenly by more than just one and itself.
To understand why 25 is composite, we can find its factors by dividing it by all of the numbers less than or equal to its square root, which is 5. We start with 1 and find that 25 divided by 1 is 25. Then we check 2, 3, 4, and 5. For each of these numbers, when we divide 25 by them, we get a remainder, which means they are not factors.
However, when we divide 25 by 5, we get an even division with no remainder. So 5 is a factor of 25. Additionally, we can divide 25 by another number, 25 itself, and get an even division without remainder. Therefore, 25 has factors of 1, 5, and 25, which means it has more than two factors, making it a composite number.
So, you made the right choice by picking option B - "It has more than two factors." Well done!
