Answer:
c'est faux parce que 3 n'est pas un diviseur de 25 et c'est pour 15 so not all divisor of 25 sommes diviseur de 15
Step-by-step explanation:
There are 34 composite numbers between 1 to 50 which are as follows: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50.
30
9 + 13 = 22
22 + 43 = 65
65 + 55 = 120
120 ÷ 4 = 30
hope this helps
