Which expression is not equivalent to the other expressions? -6(2 x - 4) -(12 x - 6) + 18 -3(4 x - 3) + 15 -4(3 x + 6)

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

yes because they have the same amount of green and blur marbles.
