The distance of the point $P(-3, 4, 5)$ from the $yz$-plane is: (in $\text{ units}$)

How far apart are the points $(2,0,0)$ and $(-3,0,0)$?

Name the octant in which each of the following points lies:
$(i) (1, 2, 3)$
$(ii) (4, -2, 3)$
$(iii) (4, -2, -5)$
$(iv) (4, 2, -5)$
$(v) (-4, 2, 5)$
$(vi) (-3, -1, 6)$
$(vii) (2, -4, -7)$
$(viii) (-4, 2, -5)$

The distance of the point $(a, b, c)$ from the $z$-axis is:

The coordinates of a point which is equidistant from the points $(0, 0, 0), (a, 0, 0), (0, b, 0)$ and $(0, 0, c)$ are given by

If $A(1, 2, 3)$ and $B(-1, -1, -1)$ are two points,then the distance $AB$ is:
