Answer:
13 units
Step-by-step explanation:
Use the distance formula, d =
, where (x2, y2) and (x1, y1) are two different points on the line.
Plug in the values:
d = 
d = 
d = 
d = 
d = 
d = 13
The answers are... For the first one Question 1. the answer would be
2x³+2x²-2x
Question 2 the answer is: x²-3x-2
Question 3 the answer is: 2x+2
Question 4 the answer is: x+7
Question 5 the answer is: <span><span><span>−15</span><span>x</span></span></span>²<span>+<span>66x</span></span><span>−<span>63
Hopes this helps! :)</span></span>

The speed of the snake is 8.95 miles per hour.
Step-by-step explanation:
Step 1:
The snake travels at a speed of 20 meters in 5 seconds.
We will need to determine the distance it covered in a single second. To do that we divide the distance covered in 5 seconds by 5.
The distance covered in 1 second 
So the snake is moving at a distance of 4 meters per second.
Step 2:
To convert the speed of the snake from meters per second to miles per hour, we multiply the speed in meters per second by 2.23694.
So to attain 4 meters per second in miles per hour, we multiply it by 2.23694.
4 meters per second
miles per hour.
Rounding this off, we get the speed of the snake as 8.95 miles per hour.
