<span>Prime numbers are the numbers that are bigger than one and cannot be divided evenly by any other number except 1 and itself. If a number can be divided evenly by any other number not counting itself and 1, it is not prime and is referred to as a composite number. Prime numbers are whole numbers that must be greater than 1. Zero and one are not considered prime numbers. Learn how to determine which numbers are prime.

Answer:
88
Step-by-step explanation:
Let's see - if there are 3/5 girls, there must be 2/5 boys. Assuming everyone in the class is binary, of course.
So 2/5 of 220 is the number of boys. When you see "of," always think multiplication!
2/5 of 220
2/5 * 220 = 88 boys in 7th grade
The number that goes into 15 and 25 is 5. So after you factor this it would be 5(3a+5b).
Answer:
(10a+5)²= 100 a( a+1) + 25
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given
(10a+5)²
By using (a+b)² = a² +2ab +b²
= (10a)²+ 2 × 10a× 5 + (5)²
= 100a² + 100a + 25
= 100 a( a+1) + 25
