19) The x coordinate of a point that lies on the x-axis is negative.

false

Step-by-step explanation:

i'm not sure if this is a true or false question, but if so, it is false

the x-axis has a positive side and a negative side, so the coordinate isn't necessarily negative. it could also be zero if the point is at the origin

hope this helps!

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
