Answer:
You should use photomath, it would be more easier for u. Oh, and by the watñy Y=12
 
        
             
        
        
        
Answer:
Formula is 132 - 8n, and there are 52 windows on 10th floor.
Step-by-step explanation:
difference = 116-124 = -8  ( 8 less windows for every floor you go up)
the first fllor has 124 windows
Formula:  

 = 132 - 8n
 = 132 - 8n
10th Floor:

 
        
             
        
        
        
Given:
Expression is

To prove:
If r is any rational number, then  is rational.
 is rational. 
Step-by-step explanation:
Property 1: Every integer is a rational number. It is Theorem 4.3.1. 
Property 2: The sum of any two rational numbers is rational. It is Theorem 4.3.2.
Property 3: The product of any two rational numbers is rational. It is Exercise 15 in Section 4.3.  
Let r be any rational number.
We have,

It can be written as

Now, 
3, -2 and 4 are rational numbers by property 1.
 is rational by Property 3.
 is rational by Property 3.
 are rational by Property 3.
 are rational by Property 3.
 is rational by property 2.
 is rational by property 2.
So,  is rational.
 is rational.
Hence proved.

Well, It depends. It is either the mathematical term for 100% - 50%, or 6e*Ehq8deh.  So, It is either 1389D9238 or c793-sk2.  So try plotting the database point. Hope this helps :)
