Answer:2.6363 so if you estimate it it is 2.64
 
        
                    
             
        
        
        
5 times n=17 because you have to use algebra
        
                    
             
        
        
        
Perimeter of rectangle=66
length of rectangle=L
width of rectangle=w
P of a rect.= 2(length)+ 2(width)
66= 2L+2w
if the length is 7in more than the width, then
L=7+w
Now we will substitute 7+w in for L. Here is our new equation:
66=2(7+w) + 2w
Solve for w 
66=14+2w+2w
66=14+4w
52=4w
w=13
L=7+13, so L=20
I hooe this is explained well enough
        
             
        
        
        
Answer:

Step-by-step explanation:
In order to find the value of n that satisfies this equation, we can perform a series of algebraic steps on it to solve for n.
  
- <em>Distribute in the 8 on the left side:</em>
- <em /> <em> </em> <em> </em>
- <em>Add 4n to both sides</em> 
  
- <em>Add 16 to both sides</em> 
  
- <em>Divide both sides by 20</em> 
  
Therefore, n=1 is the value of n that satisfies this equation.
Hope this helped!
