Given the expression,

We will have to rationalize the denominator first. To rationalize the denominator we have to multiply the numerator and denominator both by the square root part of the denominator.
![[(8x-56x^2)(\sqrt{14x-2})]/[(\sqrt{14x-2})(\sqrt{14x-2})]](https://tex.z-dn.net/?f=%20%5B%288x-56x%5E2%29%28%5Csqrt%7B14x-2%7D%29%5D%2F%5B%28%5Csqrt%7B14x-2%7D%29%28%5Csqrt%7B14x-2%7D%29%5D%20)
If we have  , we will get
, we will get  by multiplying them. And
 by multiplying them. And  .
.
So here in the problem, we will get,
![[(8x-56x^2)(\sqrt{14x-2})]/(14x-2)](https://tex.z-dn.net/?f=%20%5B%288x-56x%5E2%29%28%5Csqrt%7B14x-2%7D%29%5D%2F%2814x-2%29%20)
Now in the numerator we have  . We can check 8x is common there. we will take out -8x from it, we will get,
. We can check 8x is common there. we will take out -8x from it, we will get,


And in the denominator we have  . We can check 2 is common there. If we take out 2 from it we will get,
. We can check 2 is common there. If we take out 2 from it we will get, 

So we can write the expression as
![[(-8x)(7x-1)(\sqrt{14x-2})]/[2(7x-1)]](https://tex.z-dn.net/?f=%20%5B%28-8x%29%287x-1%29%28%5Csqrt%7B14x-2%7D%29%5D%2F%5B2%287x-1%29%5D%20)
 is common to the numerator and denominator both, if we cancel it we will get,
 is common to the numerator and denominator both, if we cancel it we will get,

We can divide -8 by the denominator, as -8 os divisible by 2. By dividing them we will get,


So we have got the required answer here.
The correct option is the last one.
 
        
             
        
        
        
Answer: Square root 85 units
Step-by-step explanation:
Given: The legs of a right triangle are 6 units and 7 units.
Let h be the hypotenuse of the right triangle.
By Pythagoras theorem of right triangle, we have 

Hence, the  length of the hypotenuse
-  Pythagoras theorem of right triangle says that the square of the hypotenuse  is equal to the sum of the squares of the other two sides.
 
        
             
        
        
        
0.3m=$4.41 
just divide $4.41/0.3= m
m=14.7
        
             
        
        
        
The height (h) of the rectangular prism is: 1.9 feet.
<h3>How to Find the Volume of a Rectangular Prism?</h3>
A rectangular prism has a length (l), height (h), and a width (w). The volume of the rectangular prism is calculated using the formula given as: V = (length)(width)(height).
Given the following parameters:
Volume of the rectangular prism = 30.45 ft^3, 
Length (l) = 6.3 ft,
Width (w) = 2.5 ft. 
Height of the rectangular prism (h) = ?
Plug in the values 
(6.3)(2.5)(h) = 30.45
15.75h = 30.45
15.75h/15.75 = 30.45/15.75
h ≈ 1.9 ft
