I think that 0 is rational, as it always is. The answer is D. I am not sure, but I hope it helps.
so it will end up at 6y-6
you need to combine everything that does not have an exponent (example. a, x, y) and you combine the ones that have exponents together. and therefore you get 6y-6 (remember positive and negative signs)
The product<span> of </span>two consecutive negative integers<span> is 462. Determine the two </span>integers<span>. ... Since this is a quadratic equation, we'll </span>get<span> one side equal to zero (by subtracting 462 from each side): ... Since </span>20*20<span> = 400 we can start near there.</span>
