I kinda forgot how to do perimeter... Find the perimeter of the following shape, rounded to the nearest tenth:

coordinate plane with quadrilateral ABCD at A negative 3 comma 2, B negative 1 comma 0, C negative 3 comma negative 2, and D negative 5 comma 0

Suppose the radius of a circle is 16. what issuppose the radius of a circle is 16. what is its circumference its circumference

What is the point-slope equation of a line with slope -5 that contains the point (6,3)

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?
