Q = x^3 â xGiven that x is a positive integer such that x ⥠75, which of the following is the remainder when Q is divided by 6?
geniusboy [140]

Answer:

A) 0

Step-by-step explanation:

Given that

Q=x^{3}-x\\\\x(x^{2}-1)\\\\x(x+1)(x-1)

Divisor = 6 = 3*2

\frac{Q}{D}=\frac{(x)(x+1)(x-1)}{6}\\\\\frac{Q}{D}=\frac{(x)(x+1)(x-1)}{2 \times 3}\\

As it can be see that x ≥ 75 and Q is product of three consecutive terms (x-1), x, (x+1) which is always completely divisible by 2, 3 and 6. So remainder is zero

If i got 10$ and spent it on a 2$ drink how much would i have
Marrrta [24]

Hi there!

This is very simple, so here's how to complete this math problem.

It looks like you're taking money away, so...

If you have 10$ and you spent 2 of them, the word 'spent' is a subtraction word, so we would subtract.

10$ - 2$ = 8$

So, therefore, you would still have 8 dollars left. :)

Hope this helps! :D
