X = width
2x + x = 3 · 13.73
3x = 41.19
x = 13.73
The width is 13.73 units.
ANSWER
The required equation is:

EXPLANATION
The given equation is

Dividing through by 225 we obtain;

This is a hyperbola that has it's centre at the origin.
If this hyperbola is translated so that its center is now at (0,5).
Then its equation becomes:

We multiply through by 225 to get;

We now expand to get;


The equation of the hyperbola in general form is

A- Stable electron configurations are likely to contain - filled energy sub-levels.
B- How many unpaired electrons are in a sulfur atom (atomic number 16)? Answer is 2
