Explain the difference between (-10)2 and -102. what are the values of each expression?

The answer is in the explanation, parentheses are very important

Step-by-step explanation:

(-10)2 you use distribution so it will be -20

and the -102 would just be some number if with out the parentheses

x=-2

step-by-step explanation:

i began by flipping the problem to give me x= on the left (keeps it clearer for me).   so my problem simply became 10x-3=4x-6.  

1)   subtract 4x from the right side, which equals 0.   you do the same to the left of the equal as the right; therefore, subtract 4x from 10x, leaving 6x on the left.

              10x-3=4x-6   :   4x-4x on the right leaves only the -6        

2)             6x-3= 0-6 :    

                6x+3=   -6

3) divide
