Answer:
5*8+14=54
Step-by-step explanation:
5*x+14= 54
so
54-14= 40
40/5=8
so x=8
 
        
             
        
        
        
First, you should solve for 

, which equals 

.  Now, solve the integral of 

=

, to get that

.  You can check this by taking the integral of what you got.  Now by the Fundamental Theorem
![\int\limits^2_0 {4x} \, dx=[2x^2] ^{2}_{0}=2(2)^{2}-2(0)^2=8](https://tex.z-dn.net/?f=%20%5Cint%5Climits%5E2_0%20%7B4x%7D%20%5C%2C%20dx%3D%5B2x%5E2%5D%20%5E%7B2%7D_%7B0%7D%3D2%282%29%5E%7B2%7D-2%280%29%5E2%3D8)
.
This should be the answer to your question, if I understood what you were asking correctly.
