Answer:
Dear math why dont you grow up and solve your own problems
Step-by-step explanation:
The answer is the option C, which is: C. √29
The explanation of this exercise is:
To solve this problem you must apply the proccedure shown below:
1- You have that:
W (-2,8,-3) and X(1,4,-1)
2- Therefore, you can calculate the magnitude as below:
|WX|=√[(1-(-2)]²+(4-8)²+[(-1-(-3)]²)
|WX|=√29
L = 2w + 4 , l + w = 80
solve using subsitiution.
(2w + 4) + w = 80
simplify / combine common
3w + 4 = 80
subtract 4 from both sides
3w = 76
divide by 3
w = 25 1/3 in
80 - 25 1/3 = 54 2/3
is it true that 54 and 2/3 inches is 4 inches more than two times 25 1/3? Yes.
Length = 54 and 2/3 inches
W = 25 and 1/3 inches
hope this helps ;D
Yes, this is a typical pythagorean triad.
Since the theorem is:
![c^{2} = a^{2} + b^{2}](https://tex.z-dn.net/?f=%20c%5E%7B2%7D%20%3D%20%20a%5E%7B2%7D%20%2B%20%20b%5E%7B2%7D%20)
And by inspection,
![5^{2}](https://tex.z-dn.net/?f=%205%5E%7B2%7D%20)
would be the hypotenuse,
![5^{2} = 3^{2} + 4^{2}](https://tex.z-dn.net/?f=%205%5E%7B2%7D%20%3D%20%203%5E%7B2%7D%20%2B%20%204%5E%7B2%7D%20)
25 = 9 + 16
RHS = 9 + 16 = 25 = LHS
Therefore, we have proved that the values fit into pythagoras' theorem, which means that the triangle is a right triangle (that is the central idea of this theorem).
