Answer 1

Step-by-step explanation:

x = 8

x = 2

Step-by-step explanation:

given points are :-

A (5,-1,7) and B (x,5,1)

also given that,

distance between these points is 9 units

now,

we know that,

distance between two points

A (x1,y1,z1) and B (x2,y2,z2)

is given by,

So, putting th respective values,

we get,

but, D = 9 units

so, putting the value and squaring both sides,

we get,

=>

=>

=>

=>

=> 'or'
