Step-by-step explanation:
hope you can understand 
 
        
             
        
        
        
Amount of FICA to be paid
($14.25 x 40) x (7.65/100) = $43.61
        
             
        
        
        
If you use the same technique from the first question, you can do:
5x+2=3x+42
2x=40
x=20
For the rest of the questions, please use the same technique if they are vertical because I can't solve all of the questions for you sorry.
        
             
        
        
        
Alright in this one, you are going to need to factor. 
The width is x
The length is 2x-4
To find the area of a rectangle is L*W
so (2x-4)(x) when distributed is 2x^2 -4x
Then put that in the equation and you have:
2x^2 -4x = 96
2x^2 -4x -96 = 0  
2x^2+12x-16x-96=0
3x(x+4)-4(x+4)=0
(3x-4)=0
(x+4)=0
x=-4
<u>x=3/4</u>
Since length isn't negative
we will use <u>3/4 as x.
</u>
Width= 0.75 ft
Length= 1.5
        
             
        
        
        
D trust me plz give points
