What is the factored form of x^9 + 27? A. (x^3 − 3)(x^6 + 3x^3 + 9)
B. (x^3 + 3)(x^6 − 3x^3 + 9)
C. (x − 3)^3(x^6 + 3x^3 + 9)
D. (x + 3)^3(x^6 − 3x^3 + 9)

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
