112=2∗56, I believe would be the answer to your question. (<span>The Prime Factors of 112: </span><span>2^4 • 7)</span>
the regular polygon would have 18 sides. because you do 180 deg-20deg=160 deg. then multiply 160 and 18 to get to2880. each exterior angle of a polygon is 20 degress. so the polygon has 360/20=18 sides. (i think)

c = -3
