Answer:
f(5) = 25
Step-by-step explanation:
f(x) = 3x + 10 
f(5) = 3(5) + 10 
f(5) = 15 + 10 
f(5) = 25 
 
        
                    
             
        
        
        
Answer:
The required formula is:
                                                            
 
Step-by-step explanation:
The total number of squares of the the first term = 4
The total number of squares of the the second term = 7
The total number of squares of the the third term = 10
so,



Finding the common difference d


As the common difference 'd' is same, it means the sequence is in arithmetic.
So
If the initial term of an arithmetic progression is  and the common difference of successive members is d, then the nth term of the sequence
 and the common difference of successive members is d, then the nth term of the sequence  is given by:
 is given by:
                          
Therefore, the required formula is:
                                                            
 
 
        
             
        
        
        
Answer: 1+1=2
 
Step-by-step explanation: Imagine you have 1 cookie, and a friend gives you 1 more, that means your total amount of cookies is 2. So that proves that 1+1=2!
 
        
             
        
        
        
Logarithm properties:

According to this, we can get:
