Answer: x = 1/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
 
        
             
        
        
        
(4n+1)=(2n-9)
the sum of four times a number and one is equal to the difference of twice the number and 9

Answer: True 
Solution:
Rearrange the equation to the LHS:
[x^2 + 8x + 16] · [x^2 – 8x + 16] - (x^2 – 16)^2 = 0
Factoring  x^2+8x+16 
x^2 - 4x - 4x - 16
= (x-4)  •  (x-4)
= = (x+4)2 
So now we have an equation 
(x + 4)^2 • (x - 4)^2 -  (x^2 - 16)^2  = 0 
Step 2: Evaluate the following:
 (x+4)2   =    x^2+8x+16
 (x-4)2   =    x^2-8x+16  
(x^2-16)2   =    x^4-32x^2+256 
(x^2+8x+16)  (x^2-8x+16  ) -  (x^4-32x^2+256 )
0 = 0
Hence True
 
        
             
        
        
        
The equations we get are
l = 6 + 2w (We get this from "The length of the rectangle is 6 more than 2 times the width.")
and
2l + 2w = 140 (We get this from the perimeter. Two times the length plus two times the width equals the perimeter of a quadrilateral.)
The first equation can be written as
l - 2w = 6
So now we have
2l + 2w = 140
l - 2w = 6
____________
Add the two equations.
We get 3l = 146
Divide by 3 on both sides.
l = 
48
Your answer is 
48
