  (3, -2)

Step-by-step explanation:

Given:

  y = -2x +4

Find:

  the value of x for y=-2

Solution:

  Put the value of y into the equation and solve for x:

  -2 = -2x +4 . . . . use -2 for y

  -6 = -2x . . . . . . . subtract 4

  3 = x . . . . . . . . . .divide by -2

The solution of interest is (3, -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
