Explanation:
Theorems about triangles identify relationships that can be used to formulate equations that can be used in the problem-solving process.
The idea with problem solving is to start with what you know, and make use of the relationships between that and what you don't know in order to find a solution.
 
        
             
        
        
        
(x - 4)(x + 3) = x^2 + 3x - 4x - 12 = x^2 - x - 12
        
                    
             
        
        
        
The answer I got is A. 25.872
