They are composite numbers because they are made up of smaller prime numbers
ex.
15 = 3*5
9 = 3*3
The numbers are 9 and -6 because 9-(-6) = 15 and 9+(-6) = 3
To find the sum of all odd numbers between 9 and 15, we first identify the odd numbers between these two values, which are 9, 11, 13, and 15. Next, we add these numbers together: 9 + 11 + 13 + 15 = 48. Therefore, the sum of all odd numbers between 9 and 15 is 48.
No 9 and 15 is not a number, they are two numbers.
The two numbers must be 6 and 9, as 6 + 9 = 15 and theer is a difference of 3 between 6 and 9. The product of 6 and 9 = 54.
ANSWER: 9, 15, 21 are not prime numbers because these numbers have factors other than 1 and themselves. Therefore, 9, 15, 21 are composite numbersFactors of 9 other 1 and itself (9) : 3Factors of 15 other 1 and itself (15): 3, 5Factors of 21 other 1 and itself (21): 3, 7
Square numbers
six, nine 9 + 6 = 15 (sum) 9 - 6 = 3 (difference) 9 x 6 = 54 (product)
9, 15, 45 are the composite factors of 45.
9 and 6
45
-3
6 and 9. 6 + 9 =15 6 x 9 = 54
