Answer:
x=7
Step-by-step explanation:
Well the equation would be 14/x-2=0, which if let number=x, and solved for the equation, 14-2x=0, x=7.

Answer:
The midpoint is 5
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two numbers is equal to
![M=(\frac{x1+x2}{2})](https://tex.z-dn.net/?f=M%3D%28%5Cfrac%7Bx1%2Bx2%7D%7B2%7D%29)
we have
The endpoints at -2 and 12
substitute the values in the formula
![M=(\frac{-2+12}{2})](https://tex.z-dn.net/?f=M%3D%28%5Cfrac%7B-2%2B12%7D%7B2%7D%29)
![M=(5)](https://tex.z-dn.net/?f=M%3D%285%29)
therefore
The midpoint is 5
Answer:
LHS = RHS
Step-by-step explanation:
![{( \sin(x) - \cos(x) ) }^{2} \\ = { \sin(x) }^{2} + { \cos(x) }^{2} - 2 \sin( x) \cos(x) \\ = 1 - \sin(x )\cos(x)](https://tex.z-dn.net/?f=%20%20%7B%28%20%5Csin%28x%29%20-%20%20%5Ccos%28x%29%20%29%20%7D%5E%7B2%7D%20%20%20%5C%5C%20%20%3D%20%20%7B%20%5Csin%28x%29%20%7D%5E%7B2%7D%20%20%2B%20%20%7B%20%5Ccos%28x%29%20%7D%5E%7B2%7D%20%20-%202%20%5Csin%28%20%20x%29%20%20%5Ccos%28x%29%20%20%5C%5C%20%3D%201%20-%20%20%5Csin%28x%20%29%5Ccos%28x%29%20)
Since,
![{ \sin(x) }^{2} + { \cos(x) }^{2} = 1](https://tex.z-dn.net/?f=%20%7B%20%5Csin%28x%29%20%7D%5E%7B2%7D%20%2B%20%20%20%7B%20%5Ccos%28x%29%20%7D%5E%7B2%7D%20%20%3D%201)
THEREFORE LHS = RHS
