Can anyone help me out with my homework?

We have some number x that we do two things to it in this exact order: divide by 3, add 8.
To isolate x or get it all by itself, we have to undo what is happening to x. We follow the order mentioned above in reverse so that we undo everything properly. Undo the "add 8" by subtracting 8 from both sides. Then you undo the "divide by 3" by multiplying both sides by 3. Check out the attached image for details and the steps on how to solve. The final answer is x = 18

ABC is a equilateral triangle .
Proof :-
Let's assume both circles as C1 and C2 [ as shown in the figure ]
- AB is the radius of circle C1
- AB is the radius of Circle C2
AC is the radius of circle C1.
BC is the radius of circle C2 .
AB and AC both are radius of circle C1 so both are equal ie AB = AC .
AB and BC both are radius of circle C 2 so both are equal ie AB = BC .
Hence we conclude that .
AB = BC = AC.
So the triangle is equilateral triangle.
