P(x)=5x^3+3x^2−6x−4.

q(x)=3x^3−2x^2−x+3.

r(x)=−x^3+2x^2−3x+7.

what is p(x)−q(x)+r(x) ?

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
