Somebody pls me i’m not trynna fail 8th !

D

Step-by-step explanation:

A represents a quadratic with a horizontal graph opening to the right;

B represents the reciprocal of x; the exponent of x is -1 here;

C represents a quadratic:  a vertical parabola

D is x = y - 2 and could be rewritten as y = x + 2.  This is a linear function.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

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
