Answer:
n=13
Step-by-step explanation:
3n-6=33
Add 6 to both sides
3n=39
Divide both sides by 3
n=13
 
        
                    
             
        
        
        
Percent means per one hundred so we can say that:
p/100≈(28)/(28+81+45+63+35)  guessing with my old eyes :)
p/100≈28/252
p≈2800/252
p≈11.11%
So rounded to the nearest 5% you'd have:
p≈10%
        
             
        
        
        
Answer:

Step-by-step explanation:
We are given the function: 

And we want to finds its zeros. 
Therefore: 

Firstly, we can divide everything by -4: 

Factor out an x: 

This is in quadratic form. For simplicity, we can let: 

Then by substitution: 

Factor: 

Substitute back: 

By the Zero Product Property: 

Solving for each case: 

Therefore, our real and complex zeros are:
