Step-by-step explanation:
Eg if a = b, b = c, then a = c
 
        
             
        
        
        
Just multiply the bases and add up the exponents.
9c^6*3c^6 = 27c^6+6 = 27c^12 <- answer

The correct answer is b. 14(m-8).
This is because it says that the weight of the boxes drew lifted were 8 pounds less than what marco lifted.  This can be represented by m-8.  You then need to multiply this by the amount of boxes that drew lifted, or 14.  
        
             
        
        
        
(2x^2 + 4x + 6) - (-3x - 5x^2 + 4)
The negative sign separating the expressions is just multiplying the rightmost expression by -1.
(2x^2 + 4x + 6) + (3x + 5x^2 - 4)
Now, let's add together terms that share the same variable. 
2x^2 + 5x^2 = 7x^2 
4x + 3x = 7x
6 + (-4) = 2
Let's combine each of these terms into one expression.
7x^2 + 7x + 2 is the final answer.
