G(n) = -3n2 - 4
h(n) = 2n + 1
Eind g(-5) – h(-5)

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
