Evaluate the expression.
5 - (4 - 2 - (6-6))
8
2
5
3

3

Step-by-step explanation:

Simplify the following:

5 - (4 - 2 - (6 - 6))

6 - 6 = 0:

5 - (4 - 2 - 0)

-0 = 0:

5 - (4 - 2 + 0)

4 - 2 + 0 = 4 - 2:

5 - 4 - 2

4 - 2 = 2:

5 - 2

5 - 2 = 3:

 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
