What's 55 times 9 help plzzz

Is it true that product of 3 consecutive natural numbers is always divisible by 6? justifyyour answer

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

If (x + 8) is a factor of f(x), which of the following must be true? both x = –8 and x = 8 are roots of f(x). neither x = –8 nor x = 8 is a root of f(x). f(–8) = 0 f(8) = 0
