Simplify (-2x - 9)(-4). 8x - 36 -8x + 36 8x+ 36 -88-36

8x+36

Step-by-step explanation:

distribute the -4

-2x times -4 + -9 times -4

8x+36

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
