To inscribe a hexagon inside a circle, to which length should you set your compass in order to draw the six vertices?
a) the radius
b) the diameter
c) half of the radius
d) it depends on the size of the circle.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
