first combine like terms so 2n + 7n which is 9n
so 9n + 7 = 13 + 3n + 8n
then combine on other side so 9n + 7 = 13 + 11n
then subtract 7 to 13 so 6
sp 9n + 6 = 11n
then subtract 9 to the other side so 2n
6 = 2n then divide all by 2 
n= 3 
 
        
                    
             
        
        
        
Answer:
c) -x^3 + x^2 - 1
Step-by-step explanation:
Given: u (x) = x^5 - x^4 +x^2 and v(x) = -x^2
(u/v)(x) = u(x)/v(x)
Now plug in the given functions in the above formula, we get
= (x^5 - x^4 + x^2) / -x^2
We can factorize the numerator. 
In x^5 - x^4 + x^2. the common factor is x^2, so we can take it out and write the remaining terms in the parenthesis.
= x^2 (x^3 - x^2 + 1) / - x^2
Now we gave x^2 both in the numerator and in the denominator, we can cancel it out.
(u/v)(x) = (x^3 - x^2 + 1) / -1
When we dividing the numerator by -1, we get
(u/v)(x) = -x^3 + x^2 - 1
Answer: c) -x^3 + x^2 - 1
Hope you will understand the concept.
Thank you.
 
        
                    
             
        
        
        
Answer:
<h2>

</h2>
Step-by-step explanation:

To find ( f - g)(x) , subtract g(x) from f(x)
That's

Since they have a common denominator that's 3x we can subtract them directly
That's

We have the final answer as
<h3>

</h3>

Answer:
16oz bag, $0.32 saved
Step-by-step explanation:
3.12/12 = 0.26
3.84/16 = 0.24
For the 12-ounce bag, it would be $0.26 per ounce. For the 16-ounce bag, it would only be $0.24 per ounce.
16*0.26=4.16
4.16 - 3.84 = 0.32
$0.38 saved
