Answer:
Width = 16 m
Length = 4 m
Step-by-step explanation:
The area of rectangular is 64m² the length of the pool is 12 m less that the width . The situation can be represented by the equation x
Area of a rectangle = Length × Width
L = W - 12
Hence:
64 = (W - 12) × W
64 = W² - 12W
W² - 12W - 64 = 0
Factor using
(W + 4)(W - 16) = 0
Width = 16m
Length = W - 12
Length = 16 m - 12 m
= 4 m
 
        
             
        
        
        
$42. 
13/2 = 6.5, 25/4 = 6.25, 42/7 = 6.
        
             
        
        
        
Answer:
(a+c)+7
Step-by-step explanation:
this is called the Associative Property
(x+y)+z=x+(y+z)
 
        
                    
             
        
        
        
Percentage is out of a 100. Therefore, 35/100
Simplify 35/100
Becomes 7/20
Fraction of 35% is 7/20
        
                    
             
        
        
        
14 and 15 are not functions while 13 and 16 are functions
