Answer 1

Answer: First we know that a circle is 360 degrees. From the center of the pentagon if you draw a segment to each point M N P Q R, you create 5 triangles from the center. So 360/5 = 72 degrees. Each 'turn' from letter to letter is a 72degree rotation about the center O.
Moving N 72 degrees maps it onto M. Moving N 144 degrees maps it onto P. Mapping P to Q would be a 72 degree rotation since they are one rotation away from each other. I hope you understand.

B. x = 1
C. all real numbers except x = 1
D. all real numbers

Answers

2(x + 7) - 1 > 15 3(x + 2) < 2x + 7
2x + 14 - 1 > 15 3x + 6 < 2x + 7
2x + 13 > 15 3x - 2x < 7 - 6
2x > 15 - 13 x < 1
2x > 2
x > 2/2
x > 1

so, x > 1 OR x < 1.....all real numbers except 1
