To find an area of a rectangle, we use this method: A = lw (length x width)
We need to replace a(rea) with 48.
48 = lw.
The following expressions can be used:
1 x 48.
2 x 24.
3 x 16.
4 x 12.
6 x 8.
8 x 6.
12 x 4.
16 x 3.
24 x 2.
48 x 1.
        
             
        
        
        
Answer:
x=27
Step-by-step explanation:
expanding the above expression we get
5x+5=4x+32
grouping numbers with coefficient of x at the left side and constant at the right side we get
5x-4x=32-5
x=27
 
        
                    
             
        
        
        
Answer:
Area = 36 
Step-by-step explanation:
There must be an error with the statement, because it is strange that the length of the frame is equal to its thickness.
Assuming that the data supplied is correct, we can do the following procedure.
Let's call L the length of the frame.
We know how much each side of the square measures.
L = 3 inches
We also know that the thickness (s) is:
s = 3 inches.
Then the area of the frame is equal to:
Area = Perimeter * thickness
Area = 4L*s
Area = 3*4*3
Area = 36 
 
        
             
        
        
        
Answer:
729
Step-by-step explanation:
I have not done this in some time so the terms may be a bit unconventional, but they work. The key to this is multiplying by -3. 
1*(-3) = -3
-3*(-3) = 9
And so on.
1, -3, 9, -27, 81, -243, 729
