Step-by-step explanation:
A parallelogram is a flat shape that has four sides. The two sets of opposite sides are parallel and of equal length to each other.
To prove that our figure is a parallelogram we first get the slope of our sides.
The formule we use to get the slope is:
m = 
- first we have the W-Z side that it's supossed to be parallel to X-Y side
if we use our formule to calculate the slope of W-Z:
=
= 8
if we use our formule to calculate the slope of X-Y:
=
= 8
- We know that parallel lines will never intersect because they have the same slope, therefore W-Z side is parallel to X-Y side
2. Then we have the W-X side that it's supossed to be parallel to Z-Y side
if we use our formule to calculate the slope of W-X:
=
if we use our formule to calculate the slope of Z-Y:
=
- We know that parallel lines will never intersect because they have the same slope, therefore W-X side is parallel to Z-Y side
Then we have to prove that the parallalel sides are equal length to each other.
The formule we use to get the distance between two points is:

We calculate the lenght of the W-Z side that it's supossed to be equal to X-Y side:
W-Z =
= 
X-Y =
= 
So the W-Z side have the same lenght to X-Y side.
We calculate the lenght of the W-X side that it's supossed to be equal to Z-Y side:
W-X =
= 
Z-Y =
= 
So the W-X side have the same lenght to Z-Y side.
We have the following functions:
f (x) = x3 - 3x2 - 13x + 15
f (x) = x4 + 3x3 - 8x2 + 5x - 25
f (x) = x3 - 2x2 - x + 2
f (x) = -x3 + 13x - 12
Factoring we have:
f (x) = x3 - 3x2 - 13x + 15 -------> x + 3
f (x) = x4 + 3x3 - 8x2 + 5x - 25 -> x + 5
f (x) = x3 - 2x2 - x + 2 ------------> x - 2
f (x) = -x3 + 13x - 12 -------------> x + 4
