Answer:
the answer would be -13n-23
Step-by-step explanation:
first you want to distribute the brackets 
-7(2+n) = -14-7n
+(-9-6n)
-9-6n
-14-7n-9-6n
combine the n value with an n value and an integer that doesn't have an n value
-7n-6n-14-9
= -13n-23
 
        
             
        
        
        
the factors of 100 are: 1, 2, 4, 5, 10, 20, 25, 50, and 100
 
        
             
        
        
        
-4x +12 -12 = -4 -12
-4x = -16
x = 4
        
                    
             
        
        
        
Invested amount (P) = $300.
Time in years (t) = 2 years.
Balance after 2 years (A) = $329.49.
Let us assume rate of interest = r % compounds annually.
We know, formula for compound interest 

Plugging values in formula, we get




Taking square root on both sides, we get 





r=0.048.
Converting it into percentage by multiplying by 100.
r=0.048 × 100
r  = 4.8 %
Therefore, the rate of interest on the account is 4.8% compounds annually.
