The vertices of a parallelogram are at (-9, 12), (-3, 12), (-5, 10), and (–11, 10). what is the perimeter of the parallelogram? round your answer to the nearest whole number?

let point A has coordinates (-9;12),B(-3;12),C(-5;10) and D(-11;10).Then the vector AB={6;0}, BC={2;-2}, CD={6;0}, AD={2;-2} and their and the length of the vectors

no not all of them.

step-by-step explanation:

some of them have a square base.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
