Which of the following are true statements about any regular polygon? Check
all that apply.
A. All of its angles are congruent.
B. It is concave.
c. All of its sides are congruent.
D. It is a closed figure.
E. It has exactly 6 sides.
F. It is convex.

For a regular polygon

A, C (otherwise it would be irregular)

D and F

Step-by-step explanation:

the 2nd line can be rewritten as y < x-3

So, any value that is less than both 4x+4 and x-3 will work

Pick any value you want for x, and figure y possibilities

x=0; x-3=-3, 4x+4=4, so y<-3 ... (0,-5) will work

I'm sure you can now come up with other pairs.
