Answer:
23,11333753
Step-by-step explanation:
1. Use The Coordinates To Find The Distances Of The Four Sides
2. The Formula For Perimeter Or A Quad =
AB + BC + CD + AD
Basically Add The Distances Of The Four Sides
So: WX + XY + YZ + WZ
![\sqrt{34} + 5 + \sqrt{61} + 2 \sqrt{5}](https://tex.z-dn.net/?f=%20%5Csqrt%7B34%7D%20%20%2B%205%20%2B%20%20%5Csqrt%7B61%7D%20%20%2B%20%202%20%5Csqrt%7B5%7D%20)
= 23,11333753

Answer:
<u>y-intercept</u><u> </u><u>is</u><u> </u><u>(</u><u>0</u><u>,</u><u> </u><u>-</u><u>2</u><u>1</u><u>)</u>
Step-by-step explanation:
For y-intercept, x = 0:
![{ \sf{y + 11 = - 2(0 + 5)}} \\ { \sf{y + 11 = - 10}} \\ { \sf{y = - 21}}](https://tex.z-dn.net/?f=%7B%20%5Csf%7By%20%2B%2011%20%3D%20%20-%202%280%20%2B%205%29%7D%7D%20%5C%5C%20%7B%20%5Csf%7By%20%2B%2011%20%3D%20%20-%2010%7D%7D%20%5C%5C%20%7B%20%5Csf%7By%20%3D%20%20-%2021%7D%7D)
The two angles are adjacent on a straight line so they are supplementary. Thus 8x+5+13x-14=180
21x-9=180
21x=189
x=9
.44 should be the right answer
