A ) Length = 5 - 2 x
Width = 3 - 2 x
The area of the bottom:
A = L  x  W = ( 5 - 2 x ) ( 3 - 2 x ) = 15 - 10 x - 6 x + 4 x² = 
= 4 x² - 16 x + 15
b ) 4 x² - 16 x + 15 = 10
4 x² - 16 x + 5 = 0
x = (16 - √(256 - 80))/ 8 = ( 16 - 13.266 ) / 2
x = 0.34 in
        
             
        
        
        
This problem basically already gives you X, you just have to simplify.
To complete this problem all you have to do is divide 11 by 9.6
11 / 9.6 = 1.15
So X = 1.15
        
                    
             
        
        
        
Answer: Answers are in the steps read carefully! 
 
Step-by-step explanation:
A) 3x^2 - 7x + 2 To factor this polynomial, you have to find two numbers that their product is 6 and their sum is -7.  The numbers -1 and -6 works out because -6 times -1 is 6  and -6 plus -1 is -7. 
Now rewrite the polynomial as 
 3x^2 - 1x - 6x + 2   Now group it  
(3x^2 - 1x) (-6x+2)  Factor it by groups 
x (3x -1)  -2(3x -1)    Now factor out 3x-1   
(3x -1) (x-2)  Done!     
B)  2x^2 - x -3     Now the same way.You will have two numbers that  their product is -6 and their sum is -1. You may be wondering how I get -6 .I get -6 by multiply the leading coefficient  2 by the constant -3.  The numbers -3 and 2 works out. Because -3 times 2 is -6 and -3 plus 2 is -1. 
  Rewrite the polynomial as 
2x^2 +2x - 3x -3     GRoup them and factor them 
 (2x^2 + 2x)  (-3x-3)  
 2x(x+1) -3(x+1)  Factor out x+1 
(x+1) (2x -3) Done!   
C) 3x^2 - 16x - 12   Find two numbers that their product is -36 and their sum is -12. The numbers -18 and 2 works out because -18 times 2 is -36 and -18 plus 2 is -16. 
Rewrite the polynomial 
 3x^2 +2x -18x - 12   GRoup them 
  (3x^2 + 2x)   (-18x - 12)   Factor them 
 x (3x +2) -6(3x +2)  Factor out 3x+2 
 (3x+2) (x -6)  Done !
