Which of the following is the proper notation used to express a point in the three-dimensional coordinate plane?

The answer is : B. (x, y, z)

Hope this helps ✌️

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .
