Answer:
   2, 3
Step-by-step explanation:
If the first integer is x, then the second is x+1. The given relation is ...
   x +3(x+1) = 11
   4x = 8 . . . . . . . . subtract 3
   x = 2 . . . . . . . divide by 4
The integers are 2 and 3.

<em>Check</em>
   2 + 3(3) = 2+9 = 11
 
        
             
        
        
        
For this case we have that by definition, the area of a circle is given by:

Where:
r: It is the radius of the circle
As data we have that
Then, replacing we have:

Taking 
A = 113.04
So, the pool area is 
Answer:

 
        
             
        
        
        
4.781, 4.782,4.783,4.784,4.785 
I can't explain though:(

From the simplified form of the expression, the third term on expansion is  
 
Given the expression 
- For binomial expansion, the power of 3x will be decreasing while y^3 will be increasing.
On expansion, the resulting expression will be:
Simplify the result to have:
From the simplified form of the expression, the third term on expansion is
