Answer:
C. 60 sq. units
Step-by-step explanation:
15 times 8 is 120.
120 divided by 2 is 60.
 
        
                    
             
        
        
        
F(a+h)=2(a+h)³=2(a³+3a²h+3h²a+h³)
the second choice is the correct answer.
        
             
        
        
        
We can round 5.65 up to 6 and 3.4 down to 3. 
3 * 6 = 18
now let's see how close our estimate is to the real answer
5.65 * 3.4 = 19.21
Our answer was pretty close to the real answer!
Hope I helped!
