Associative means that you can move the parenthesis around the problem and still get the same answer. like (4+2)+3=4+(2+3) 
first & sixth are the true
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Factoring  x2-6x-30 
The first term is,  x2  its coefficient is  1 .
The middle term is,  -6x  its coefficient is  -6 .
The last term, "the constant", is  -30 
Step-1 : Multiply the coefficient of the first term by the constant   1 • -30 = -30 
Step-2 : Find two factors of  -30  whose sum equals the coefficient of the middle term, which is   -6 .
      -30    +    1    =    -29	
      -15    +    2    =    -13	
      -10    +    3    =    -7	
      -6    +    5    =    -1	
      -5    +    6    =    1	
      -3    +    10    =    7	
      -2    +    15    =    13	
      -1    +    30    =    29	
 
        
                    
             
        
        
        
Answer:
256, 3125/2, 64
Step-by-step explanation:
4^2(4^2)=16(16)=256
5^4(5)/2^1=625(5)/2=3125/2
(5+3)^2=8^2=8*8=64
