Answer:
48x⁷ - 64x + 9
Step-by-step explanation:
Step 1: Write out expression
4x(12x⁶ - 4²) + 9
Step 2: Evaluate exponent
4x(12x⁶ - 16) + 9
Step 3: Distribute
48x⁷ - 64x + 9
 
        
                    
             
        
        
        
Sin = opposite/hypothenuse 
Given opposite = 16
Hypothenuse = ?
Use Pythagorean theorem to find hypothenuse 
12^2 + 16^2 = h^2
144 + 256 = h^2
h^2 = 400, h = 20
You know hypothenuse is 20
Opposite/hypothenuse 
Solution: 16/20 
Simplify if you need to (4/5)
