diagonals ( n is the number of sides )
Answer:
m = 1
Step-by-step explanation:
Slope is defined as m = rise / run.
As we move from (2,2) to (4,4), x increases by 2 and y increases by 2.
Thus, the slope of this line is m = rise / run = 2/2 = 1: m = 1
<em>Answer:</em>
<em>1. 65 coins</em>
<em>2. 79 - (23 + 22 + 20) = n</em>

Answer:

Step-by-step explanation:
Surface area → area of 2 bases + area of 6 rectangles
Area of base is given
Area of rectangle → length × width

The answer is: 8 red marbles!
This is because the equation can be written out like this
Blue to red - 3:2
Now it is, blue to red - 12:x
We have to think, what is the difference from the first equation to the second. We know the number 3 times 4 = 12, so we would do the same for the red, 2 times 4=8
