Answer:
x^3-x^2-17x+12
Step-by-step explanation:
(x+4)(x^2-5x+3)
x^3-5x^2+3x+4x^2-20x+12
x^3-5x^2+4x^2+3x-20x+12
x^3-x^2-17x+12
 
        
                    
             
        
        
        
Answer:  Second option.
Step-by-step explanation:
 Let be "e" the number of easy puzzles Tina solved and "h"  the number of hard puzzles Tina solved.
 Set up a system of equations:
 
 You can use the Eliminationn Method to solve this system of equations:
-  Multiply the first equation by -30.
- Add the equations.
- Solve for "h".
 Therefore, through this proccedure, you get:
