Answer:
4
The Problem:
Compute the distance between 8-2i and 4-2i.
Step-by-step explanation:
This is equivalent to asking the distance from point (8,-2) to point (4,-2).
The nice thing about this problem is that the y-coordinates are the same which means it is just a horizontal distance. It can either be counted or just find the distance between the x's by finding the positive difference; that is do larger minus smaller.
8-4=4.
The distance between the points is 4.

Answer:
Step-by-step explanation:
Answer:
3k^2 -k+5
reason:
when adding two equations together, you combine like terms.
First, add -2 to 7 to get 5
Then, add k, or 1k, to -2k, which gives you -1k, or just -k
3k^2 stays the same because there are no like terms in the other equation to combine it with
