The values of x and y vary directly and one pair of values are given.
Write an equation that relates x
and y. Simplify completely.
x = -4, y = 6
[ ?
y =
х

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

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
