If f(x) = x²+ x - 1 and g(x) = 4x - 7 verify the following
i) (f + g)(2)= f(2) +g(2)
ii)(f/g) (4) = (f(4) )/(g(4) )​

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
