Answer:
Rectangle
Step-by-step explanation:
The given quadrilateral has coordinates at: P (3,7), Q (-1,7), R (3, -1) and S (-1, -1).
The length of PQ is given by:
![|PQ|=|3--1|=|4|=4](https://tex.z-dn.net/?f=%7CPQ%7C%3D%7C3--1%7C%3D%7C4%7C%3D4)
The length of QS is ![|QS|=|7--1|=|8|=8](https://tex.z-dn.net/?f=%7CQS%7C%3D%7C7--1%7C%3D%7C8%7C%3D8)
The length of RS is ![|RS|=|3--1|=|4|=4](https://tex.z-dn.net/?f=%7CRS%7C%3D%7C3--1%7C%3D%7C4%7C%3D4)
The length of PR is ![|PR|=|7--1|=|8|=8](https://tex.z-dn.net/?f=%7CPR%7C%3D%7C7--1%7C%3D%7C8%7C%3D8)
The slope of PQ is ![\frac{7-7}{3--1}=0](https://tex.z-dn.net/?f=%5Cfrac%7B7-7%7D%7B3--1%7D%3D0)
The slope of QS is ![\frac{-1-7}{-1+1}= \infty](https://tex.z-dn.net/?f=%5Cfrac%7B-1-7%7D%7B-1%2B1%7D%3D%20%5Cinfty)
The slope of RS ![\frac{-1--1}{-1-3} =0](https://tex.z-dn.net/?f=%5Cfrac%7B-1--1%7D%7B-1-3%7D%20%3D0)
The slope of PR is ![\frac{-1-7}{3-3}=\infty](https://tex.z-dn.net/?f=%5Cfrac%7B-1-7%7D%7B3-3%7D%3D%5Cinfty)
The quadrilateral has pair of parallel sides equal and adjacent sides perpendicular.
This is a rectangle
Answer:
get a pc dont delete
Step-by-step explanation:
you can't
Or you can just say it is rounded to 0
f1×f2-f3=(-5x+4)×(-6x-5)-(-9x+2)=30x^2-24x+25x-20+9x-2=30x^2+10x-22=(5x+1)^2-23
