Given that:
(x+2)(2x-5)=54
We have:

Using the quadratic formula, this is approximately 5.66, so rounded to the nearest whole number, our answer is 6.
 
        
        
        
Answer:
See below.
Step-by-step explanation:
If the exponent is a/b  then a is the power and b is the value of the radical.
Example:   x^2/3  =   ∛x².    2 is the power and 3 is the radical.
Answers: 
1)  7^2/3 =  ∛7²
5)  √3 = 3^1/2
9)  (∛27)⁴ = 27^4/3 =  3^4 = 81.
 
        
                    
             
        
        
        
Area= Length* Width
⇒ 12 ft^2= 5 ft* Width
⇒ Width= 12 ft^2/ 5 ft
⇒ Width= 2.4 ft
The width is 2.4 ft~
