Answer:
B and D 
Step-by-step explanation:
First, you have to solve the first equation. (Hint: you use the distributive property.)
2(5x + 2 + x)
10x + 4 + 2x
12x + 4
We can already see that B is correct and A is incorrect. 
Now to solve C and D.
C = 2(5x + 3)
10x + 6
This is incorrect.
D = 2(6x + 2)
12x + 4
This is correct. 
 
        
                    
             
        
        
        
Answer:
assuming its an annual interest
Okay so 6 percent interest, the bank is paying you. 
So with this it’s 6 percent of 1500 and add it to 1500. 
You can always find 6 percent of 1500 and then add but here’s a short cut. 
Your principle (beginning) balance is 1500. 
That’s already 100 percent since thats yoru original value. 
You then get added 6 percent interest. 
We are jsut adding 6 percent to 100 percent so 106 percent. 
Now we solve normally and you’d get the answer faster. 
106 percent is 106/100 or 1 3/5 or 1.06 
now we multiply
1500 * 1.06 = 1590 
Your final balance would be 1590 after the 6 percent interest is added.
