Answer: The answer is (d) Compounding. 
 
Step-by-step explanation:  We are given four options out of we are to select the best way through which we can achieve significant increases in interest after all in a savings account.
Increases in principle and increases in time will not give the result, because we are talking about a fixed amount of money for a fixed time.
Also, increases in interest is not in our hand.
So, only we can do is compounding. Here, in same amount of money and time, the rate of interest will automatically increase.
Thus, the correct option is (d) Compounding.
 
        
             
        
        
        
B is the correct answer.
We are adding the border of x thickness to all 4 sides of the table.  This makes the new width of the table 36+x+x = 36+2x and the new length of the table 72+x+x=72+2x.  To find the area, we multiply the length and width:
(36+2x)(72+2x) = 3006
Multiplying the binomials, we get:
36*72 + 36*2x + 2x*72 + 2x*2x = 3006
2592 + 72x + 144x + 4x² = 3006
Combining like terms gets us
2592 + 216x + 4x² = 3006
Subtract 3006 from both sides:
2592 + 216x + 4x² - 3006 = 3006 - 3006
-414 + 216x + 4x² = 0
Writing in standard form we have
4x²+216x-414=0
        
             
        
        
        
Answer:  x < -9
Step-by-step explanation:
-8x > 72          
x < -9      when dividing a negative number in an inequality, change the sign to opposite.
the number are less than -9.
