Answer:

Step-by-step explanation:
The shortest distance d, of a point (a, b, c) from a plane mx + ny + tz = r is given by:
--------------------(i)
From the question,
the point is (5, 0, -6)
the plane is x + y + z = 6
Therefore,
a = 5
b = 0
c = -6
m = 1
n = 1
t = 1
r = 6
Substitute these values into equation (i) as follows;




Therefore, the shortest distance from the point to the plane is 
I think its 24 because 6*2 equals 12 but you cant multiply 8 by anything to get 12
with 24 6*4 equals 24 and 8*3 equals 24
Answer:
3 + 5i
Step-by-step explanation:
Given
- 2i + (9 - 3i) - (6 - 10i) ← distribute parenthesis
