Answer:
They went up 16 levels.
Step-by-step explanation:
You can find that by finding the distance from -2 to 14.
To find the distance from two numbers, 
and 
, we can substitute both in the formula 
, where d is the distance between them.
If you’re talking about answers a would be the option first b would be 2nd and c would be 3rd
Answer:
The perimeter of the rectangle is 18 units.
Step-by-step explanation:
The image included below presents the location of the points on the Cartesian plane. From Geometry we get that the perimeter (
), dimensionless, of the rectangle is the sum of its four sides. That is to say:
(1)
Where 
, 
, 
and 
are the sides of the rectangle, dimensionless.
Each side value is found by means of the Pythagorean Theorem:
![AB = \sqrt{[2-(-1)]^{2}+(1-1)^{2}}](https://tex.z-dn.net/?f=AB%20%3D%20%5Csqrt%7B%5B2-%28-1%29%5D%5E%7B2%7D%2B%281-1%29%5E%7B2%7D%7D)
![BC = \sqrt{(2-2)^{2}+[(-5)-1]^{2}}](https://tex.z-dn.net/?f=BC%20%3D%20%5Csqrt%7B%282-2%29%5E%7B2%7D%2B%5B%28-5%29-1%5D%5E%7B2%7D%7D)
![DA = \sqrt{(-1-1)^{2}+[1-(-5)]^{2}}](https://tex.z-dn.net/?f=DA%20%3D%20%5Csqrt%7B%28-1-1%29%5E%7B2%7D%2B%5B1-%28-5%29%5D%5E%7B2%7D%7D)
And the perimeter of the rectangle is:
The perimeter of the rectangle is 18 units.
Congrats on getting that far!
From here, simplify the equation by dividing each term by the greatest common factor: 6.
36B + 30C = 822600 becomes 6B + 5C = 137100
Now you have stackable simultaneous equations that you can easily work with:
6B + 5C = 137100
B + C = 24500
Multiply the terms in the second equation by either 6 or 5 so that you can subtract the second equation from the first equation and cancel out the B or C, respectively.
Example:
6B + 5C = 137100
minus 5B + 5C = 122500
equals B = 14600
Then plug your answer into the B + C = 24500 equation to find C.
Finally plug B and C into the A + C + B = 49000 equation to get A.
