Hello!
![-1-4s=8](https://tex.z-dn.net/?f=-1-4s%3D8)
![-1-4s+1=8+1](https://tex.z-dn.net/?f=-1-4s%2B1%3D8%2B1)
![-4s=9](https://tex.z-dn.net/?f=-4s%3D9)
![\frac{-4s}{-4}=\frac{9}{-4}](https://tex.z-dn.net/?f=%5Cfrac%7B-4s%7D%7B-4%7D%3D%5Cfrac%7B9%7D%7B-4%7D)
![s=-\frac{9}{4}](https://tex.z-dn.net/?f=s%3D-%5Cfrac%7B9%7D%7B4%7D)
Explanation: <u><em>This question is super easy for me. First you had to do add 1 from both sides. It gave us -1-4s+1=8+1, then simplify, and it gave us -4s=9. You can also divide by -4 from both sides. It gave us -4s/-4=9/-4, and simplify. And the answer it gave us is s=-9/4 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie </em></u>
Answer:
![x=24.5\\](https://tex.z-dn.net/?f=x%3D24.5%5C%5C)
Step-by-step explanation:
So we have the equation:
![(5x-25)+(3x+9)+180](https://tex.z-dn.net/?f=%285x-25%29%2B%283x%2B9%29%2B180)
Combine like terms:
![(5x+3x)+(-25+9)=180](https://tex.z-dn.net/?f=%285x%2B3x%29%2B%28-25%2B9%29%3D180)
Add:
![8x-16=180](https://tex.z-dn.net/?f=8x-16%3D180)
Add 16 to both sides:
![8x=196](https://tex.z-dn.net/?f=8x%3D196)
Divide both sides by 8:
![x=24.5\\](https://tex.z-dn.net/?f=x%3D24.5%5C%5C)
So, our answer is 24.5 :)
<span>Im pretty sure the answer is C because the polynomial discriminate is 100 hope this helps
