Answer: -3

Step-by-step explanation:

(2a^x +1/2 b^x)^2 thank you!!!!!!!!!!!!!!!!!!!1
kogti [31]
Note that (a+b)^2 = a^2 + 2ab + b^2.

Therefore, 
                                                                              b^x         (b^x )^2
<span>(2a^x +1/2 b^x)^2 becomes (2a^x)^2 + 2(2a^x)(-------- ) + ------------
                                                                                 2               4

LCD is 4.  Thus, we have

I REALLY NEED HELP ON THIS QUESTION!
Tcecarenko [31]

Answer:  The correct answer is:  [A]:  " x  =  - 1/2 " .

_______________________

Step-by-step explanation:

_______________________

Given:

4x − 6  =  10x − 3  ;   Solve for "x" ;

Let us add "3" to each side of the equation;  

 and subtract "4x" from each side of the equation:

______________________

4x − 6 + 3 − 4x  =  10x − 3 + 3 − 4x  ;

______________________

to get:

______________________

               -3  = 6x  ;

______________________    

      ↔  6x  =  -3  ;

______________________

Now, divide Each Side of the equation by "6" ;

   to isolate "x" on one side of the equation;

   and to solve for "x" ;

______________________

            6x / 6  =  - 3 / 6  ;

to get:

                x  =  - 3/ 6 ;

             

                    = -\frac{3}{6} = -\frac{(3/3)}{(6/6)}=-\frac{1}{2}  .

______________________

        →  which is:  Answer choice:  [A]:   "  x = -1/2  " .

______________________

Hope this helps!

  Wishing you well in your academic endeavors!
