(x+3)(x-1/4)=x^2+11/4-3/4
For a polygon,
the <span>Sum of Interior Angles = (Number of Sides -2) • 180 degrees
hexagon = 6 sides so
(6 -2) * 180
all angles sum to 720 So each angle = (720/6) = 120 degrees
</span>
<span>-5p^3(4p^2 + 3p - 1) = -20p^5 - 15p^4 + 5p^3
answer is
A. first one
</span>-20p^5 - 15p^4 + 5p^3
