A parallelogram has three of its vertices at (-1, 0), (2, 4) and (2, -4). What is the positive difference between the greatest possible perimeter and the least possible perimeter of the parallelogram?

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

how many friends does he have? i think some of the information got cut off in the problem.

okey so the slope is -3/5 and the y -intercept is 7/5

hope this if needed hmu
