Answer:
Number of students(n1)= 4,402
Step-by-step explanation:
Giving the following information: 
Number of students= 4,512
Declining rate= 2.5%
<u>To calculate the number of students next year, we need to use the following formula:</u>
Number of students (n+x)= number of students (n0) / [(1+declining rate)^(n+x)
x= number of years
Number of students(n1)= 4,512/1.025
Number of students(n1)= 4,402
 
        
             
        
        
        
First we need to find the the answer to both the square root of 49 and 9.
The "square root" is a term referring to a number, multiplied by itself (x • x) would be = to your square root.
So for example: Square root of 16 = 4 because 4*4=16 
So lets get out numbers:


Now you multiply 3*7 (or 7*3) and you get 21.
Final answer: 21
