Answer:
8N - 4 border tiles.
Step-by-step explanation:
There are 4 border tiles in each corner and between the tiles there are N-2 tiles along the 4 sides.
So the number of border tiles
= 4+ 4(N - 2)
= 4 + 4N - 8
= 8N - 4.
Answer:
67 degrees
Step-by-step explanation:
first find angle abc by subtracting 68 from 101 == 33
then add it to half of 68 (34) to get angle abe
we know it is half because if there is a bisector, both angles cbe and ebd are equal

Answer:
Yes, "y" varies directly with "x"
The constant of variation is:
Step-by-step explanation:
Constant variation equation has the following form:
Where "k" is the constant of variation.
You can notice in the table the when "x" increases, "y" increases and the ratio between them is always the same.
To find "k" you need to pick any a point from the table, subsitutte the coordinates into and solve for "k". Then:
