Leela is convinced that (a+b)2 = a2 + b2

(a+b)^2=a^2+2ab+b^2

Step-by-step explanation:

(a+b)^2=(a+b)(a+b)

Use foil by multiplying a by a+b then b by a+b

(a*a)+ab+ab+(b*b)= a^2+2ab+b^2

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

no he doesnt because "-16' is negatiive
