Answer:
6x + 1
Step-by-step explanation:
1. (10x + 3) + (-4x -2) --> sum means to add.
2. Combine like terms --> 10x - 4x = 6x; 3 - 2 = 1.
3. 6x + 1
 
        
                    
             
        
        
        
|x| this means absolute value making what ever number in the inside positive UNLESS you have a negative out front. Ex |8|=8. -|8|=-8. |-8|=8
        
             
        
        
        
Only 4 because the only way he cant get a pair is if he picks up a different colour to the previous sock, so by the fourth he will have picked up at two of at least one colour
        
             
        
        
        
Answer:
No, Sorry.
Step-by-step explanation:
Since the bases are different, you'll have to change them even if they have a exponent or not. If you dunno how to make the denominators the same, just multiply the two by eachother.
Example) 1/2 - 3/4

 Multiply 2 and 4 together, and then multiply the 4 to the one also. Multiply 2 to four and also to the 3.

The subtract from there. 

and then Reduce (if needed.)
