Answer:

Hence, ption B is true.
Step-by-step explanation:
Given the expression

solving the expression

as


so the expression becomes

Group like terms
                                         
Add similar elements
                                         
Therefore, we conclude that:

Hence, option B is true.
 
        
                    
             
        
        
        
Answer: -258
<u>Step-by-step explanation:</u>
Given the sequence {-8, 16, -32, 64, ... , a₇} we know the following
- the first term (a₁) = -8
 - the common ratio (r) = -2
 - the number of terms (n) = 7
 
Input the information above into the Sum formula:

 
        
                    
             
        
        
        
Answer:
$16
Step-by-step explanation:
Looking at the Price for 5 Items (10 dollars), That means the Price Per Item Is 2 dollars. Now we know the Cost per Item, We need to multiply the Cost per item by 8 (2*8) making it 16. 
 
        
                    
             
        
        
        
Answer:
explicit formula for an, the nth term of the sequence 19,24,29 

Step-by-step explanation:
We need to Write an explicit formula for an, the nth term of the sequence 19,24,29 
In the sequence the First term a₁= 19
Common Difference d= 5
The Formula used for explicit formula is: 
Where d is common difference and n is nth term of sequence.
So, explicit formula for an, the nth term of the sequence 19,24,29
