Your answer is c, an obtuse triangle because if the two side lengths are the same length along with a longer side, it become obtuse
let me know if you have any other questions

Answer:
![x=-\frac{24}{7}\\x=0](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B24%7D%7B7%7D%5C%5Cx%3D0)
Step-by-step explanation:
1. You must clear the absolute value bars.
2. You have two cases: a positive case and a negative case.
3. First, you can solve the positive case as following:
![7x+12=12\\7x=12-12\\x=0](https://tex.z-dn.net/?f=7x%2B12%3D12%5C%5C7x%3D12-12%5C%5Cx%3D0)
4. Now, you must solve thie negative case as you can see below:
![-(7x+12)=12\\-7x-12=12\\-7x=24\\x=-\frac{24}{7}](https://tex.z-dn.net/?f=-%287x%2B12%29%3D12%5C%5C-7x-12%3D12%5C%5C-7x%3D24%5C%5Cx%3D-%5Cfrac%7B24%7D%7B7%7D)
5. Therefore, the answer is:
![x=-\frac{24}{7}\\x=0](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B24%7D%7B7%7D%5C%5Cx%3D0)
