Which of the expressions are not polynomials? check all that apply.
a. 8x^10 + 2x^5
b. 5x^-1 + 4x^-2
c. x^5 + 2
d. 5x^5
e. x2 +(square root of x) + 4
f. x^2-(square root of x ) -3

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
