Answer:
   5a^2 +2a
Step-by-step explanation:
Like terms are ones with the same exponent of x. They can be combined.
   3a^2 +2a +2a^2
   = (3a^2 +2a^2) +2a
   = (3+2)a^2 +2a
   = 5a^2 +2a
 
        
                    
             
        
        
        
I = PRT
P = 8000
T = 4
R = 12%...turn to decimal...0.12
now we sub
I = (8000)(0.12)(4)
I = 3840 <==
