The answer is the first choice. 
        
             
        
        
        
B.
because {1,1,3,5,8}
 {2,2,4,6,9}
you're just counting the numbers after the one that was given to you.
        
             
        
        
        
Answer:
6.75$
Step-by-step explanation:
because 15% of 45$ is 6.75$
 
        
             
        
        
        
We can see that they all have a 3 in common, but no greater and an x^2 in common so the answer is B: 3x^2
        
             
        
        
        
1. 2^6. 
2. 2^3.
3. 3^7
4. 6x^4
5. 4x^2
6. 12n^5
7. 9x^2
To find the answer of these questions, add the exponents. If there is whole numbers in the problem, you have to multiply the numbers. For number 7, do 3^2 and x^2. Hope this helps!
