convert the equation to the standard form of a parabola and graph the parabola the focus and the directrix y^2 - 12x - 4y + 64 =0 x^2 + 8x - 16y - 48 = 0.

Pls me this is due today and i need i will make brainliest if you me answer correctly and i will report if you try to give me a dumb answer.

Select the lengths in centimeters that would form a right triangle

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
