Subtract (5 − 2i) − (1 + 8i). which property allows you to write the expression as 5 − 2i − 1 − 8i?

What are the solutions to the equation 4x2+3x=24-x

Gh bisects fgi. find the measure of hgi •15° •21° •10° •8°

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- 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. 3- 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 part b?
