Answer:
   16x -2
Step-by-step explanation:
You know how to compute the perimeter of a rectangle of length L and width W:
   P = 2(L+W)
Here, you're asked to use the given algebraic expressions for length and width and simplify the result of putting those in the perimeter formula.
   P = 2((5x-2) +(3x+1))
   P = 2(8x -1)
   P = 16x -2 . . . the perimeter of the rectangle
 
        
             
        
        
        
Multiplying 20×1/2 is the same as dividing 20 by 2. Which means the answer is 10.
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
No solutions....means the lines are parallel...means ur 2 equations have to have the same slope but different y intercepts
y = 2x + 4 and y = 2x + 3
========================
Infinite solutions...means u have the same line 
y = 2x + 4 and 2y = 4x + 8....notice how if u reduce the 2nd one by dividing everything by 2 u get y = 2x + 4...same line
========================
1 solution....means ur equations will have different slopes and different y intercepts.
y = 2x + 4 and y = 4x + 2
now, u can pick which one u want :)
