Your question answers itself. You solve by graphing.
I like to subtract one side of the equation from the other, so the solutions are where the graph crosses the x-axis (the resulting function value is zero).
It can be useful to find the "turning point" of each absolute value expression (where its value is zero) and graph that and some points on either side.
Convex Polygon:
A polygon is called a convex polygon when no line segments between the points, goes inside. The boundaries of the convex polygon do not go inside and all the vertices are pointed outside away from the center. The interior angles of a convex polygon are less than 180°.
Lets simplify the given problem,
If we try using 1070 degrees as the sum of the interior angles of a convex polygon, we get:
1070 =[n - 2] x 180, where n = number of sides

n = 7.94 number of sides. Since this is not a whole number, will simply round it up to 8.
Hence the number of sides is 8

Liam can conclude that the cost of the memberships for both gyms are equal.
The circumference is pi times the diameter of the circle. The radius is half of the diameter. In this case, the radius is then 36.
