The distance formula is:
![d= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B%28x_1-x_2%29%5E2%2B%28y_1-y_2%29%5E2%7D%20)
We are given two points in the form (x,y), so plug in the values to the distance formula:
![d= \sqrt{(-10-15)^2-(12-12)^2}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B%28-10-15%29%5E2-%2812-12%29%5E2%7D%20)
Next we can simplify. We know that 12-12 is 0, so we can drop it from the equation, as it will not affect our answer. Also, we know that -10-15 is -25:
![d= \sqrt{(-25)^2}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B%28-25%29%5E2%7D%20)
The square and square root cancel each other out leaving us with 25.
The answer is 25.

I think this should be the expression
X = 14 + 50

Answer: C) nonmetal</h3>
This element has 8 protons, so element is oxygen. I recommend looking at the periodic table of elements. At standard temperature and pressure (STP), oxygen is a gas, so that puts it in the nonmetal category.
Side note: Metalloids are a collection of elements where they share properties of metals and nonmetals (in a way they're on the fence).
