50 points an unknown number x is at most 20. which graph best represents all the values of x? (1 point) number line graph with closed circle on 20 and shading to the right. number line graph with open circle on 20 and shading to the right number line graph with closed circle on 20 and shading to the left. number line graph with open circle on 20 and shading to the left

At most means it can either equal 20 or be less than 20.

On a number line, there would be a closed circle on the number 20 and the area to the left of 20 would be shaded.

Number line graph with closed circle on 20 and shading to the left.

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

b.my answer is b.
