Answer:
(f-g)(x) = x^4 - x^3 - 4x^2 - 3 
Step-by-step explanation:
(f-g)(x) = x^4 - x^2 + 9 - (x^3 + 3x^2 + 12)
(f-g)(x) = x^4 - x^2 + 9 - x^3 - 3x^2 - 12
(f-g)(x) = x^4 - x^3 - 4x^2 - 3 
 
        
             
        
        
        
Answer:
24
Step-by-step explanation:
Since the ladder, wall, and ground form a right triangle, you can use this formula:
A squared + B squared = C squared
A = 7 feet
C = 25 feet
B = distance the ladder will reach
49 + B squared = 625
B squared = 625 - 49
B = square root of 576
B = 24 feet
 
        
                    
             
        
        
        
Answer:
15
Step-by-step explanation:

Cross multiply to get 25x = 375
Divide each side by 25 to get x = 15
