Answer: 42
Step-by-step explanation:
To solve this question, we have to find the lowest common multiple of 9, 12 and 18 and then add 6. This will be:
Multiple of 9 = 9, 18, 27, 36, 45
Multiple of 12 = 12, 24, 36, 48, 60
Multiple of 18 = 18, 36, 54, 72, 90
The lowest common multiple is 36. Ww will then add 6. This will be:
= 36 + 6
= 42
