Answer: The required value is

Step-by-step explanation: The given functions are:

We are given to find the value of 
We know that, if s(x) and t(x) are any two functions of a variable x, then we have

Therefore, we have

Thus, the required value is

Answer: 7.5
Step-by-step explanation:
use pythagorean theorem
13^2 + b^2 = 15^2
- 13^2
b^2 = 56 - square root
= 7.5
Let's solve this by creating an equation.
Let X = the second factor
