Answer: second option.
Step-by-step explanation:
In order to solve this exercise, it is necessary to remember the following properties of logarithms:

In this case you have the following inequality:

So you need to solve for the variable "x".
The steps to do it are below:
1. You need to apply
to both sides of the inequality:

2. Now you must apply the properties shown before:

3. Then, rounding to the nearest ten-thousandth, you get:

The formula subject to q is 
Explanation:
The given formula is 
We need to determine the formula subject to q.
<u>The formula subject to q:</u>
The formula subject to q can be determined by solving the formula for q.
Let us solve the formula.
Thus, we have;

Subtracting both sides by 5p, we have;

Dividing both sides by 5, we get;

Thus, the formula subject to q is 
In an isosceles triangle, two sides are equal to each other. So, we know that the third side is either 6 or 15 inches.
If the third side is 6 inches, it would not make a triangle. The sum of any to sides of a triangle must be larger than the third side. However, 6+6 is LESS than 15, so 6 inches would not be the answer.
By process of elimination, the third side is 15 inches. Good luck!
