Sum of interior angles of polygon
(n-2) × 180 = (5 - 2) x 180 = 3 x 180 = 540
so
2x + 142 + 2x + 3x + 14 + 3x + 14 = 540
10x + 170 = 540
10x = 370
x = 37
m<M = 3x + 14
m<M = 3(37) + 14
m<M = 111 + 14
m<M = 125
The c is a constant term.
Simply looking at each factor the GCF of all of them would be 2x. Therefore, you would separate the 2x from the polynomial.
2x ( <u>3x^2</u> +<u>4x</u> <u>-2</u> )
because when multiplied again you get the original polynomial.
