Lol I was looking for help for this question but I couldn't find it so I had to figure it out my self and the answer is 40
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
To solve the question we refresh our knowledge of the quotient rule. 
For a function f(x) express as a ratio of another functions u(x) and v(x) i.e 
 , the derivative is express as
, the derivative is express as 

from 
we assign u(x)=lnx and v(x)=x^2
and the derivatives 
 .
.
Note the expression used in determining the derivative of the logarithm function.it was obtain from the general expression of logarithm derivative i.e 
If we substitute values into the quotient expression we arrive at 

 
        
             
        
        
        
Answer:

Answer:
12 x 10 = 120
120 divided by 2 = 60
Formula of a triangle:
B(base) x H(height) x 1/2(basically dividing by 2)
 
        
             
        
        
        
The value of x is 5/8.
<u>Step-by-step explanation</u>:
Given, 
- The lines PQ and RS are parallel to each other.
- slope of PQ= x-1/4
- slope of RS = 3/8
The slopes of parallel lines are equal.
slope of PQ = slope of RS
⇒ x-1/4 = 3/8
⇒ (4x-1)/4 = 3/8
⇒ 8(4x-1) = 4(3)
⇒ 32x-8 = 12
⇒ 32x = 20
x = 20/32
x = 5/8
