I need the answer to the image attached

D

Step-by-step explanation:

let y = f(x) and rearrange making x the subject

y = ( multiply both sides by x )

xy = 8 ( divide both sides by y )

x =

Change y back into terms of x

(x) = ← with restriction x ≠ 0 → D

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

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
