`|z-1| + |z+3|=8` then find `|z-4|`

If |z-1|+|z+3|<=8, then the range of values of |z-4| is

If |z-1|+|z+3|<=8 then the range of value of |z-4| is

If |z-1|+|z+3|<=8 , then the range of values of |z-4| is

If |z-1|+|z+3|<=8 , then the range of values of |z-4| is

If the complex number z satisfies the equations |z-12|/|z-8i|=(5)/(3) and |z-4|/|z-8| =1, "find" z.

If z_1 = 3 + 4i , z_2 = 5 - 12i and z_3 = 6 + 8i , find |z_1|, |z_2|,|z_3|, |z_1 + z_2|,|z_2 - z_3|, and |z_1 + z_3| .

If |z-1|+|z+3|le8, then the maximum, value of |z-4| is =

If |z-1|+|z+3|le8, then the maximum, value of |z-4| is =
