We have that

<span>10x - 4 = 2 ( ? )
</span>I proceed to replace the missing value with the given expression

case a-------------> <span>5x - 4
</span><span>then
</span>10x - 4 = 2 (5x-4 )--------> 10x - 4 = 10x-8--------> is not solution

case b-------------> 5x - 2
then
10x - 4 = 2 (5x-2 )--------> 10x - 4 = 10x-4--------> is  solution

 case c-------------> <span>10x - 4 
</span>then
10x - 4 = 2 (10x - 4 )--------> 10x - 4 = 20x-8--------> is not solution

 case d-------------> <span>10x - 8
</span>then
10x - 4 = 2 (10x - 8 )--------> 10x - 4 = 20x-16--------> is not solution

Find the scale factor that was used to create the dilaton below
Ne4ueva [31]

Let:

k\cdot IW=I^{\prime}W^{\prime}

Where:

k = scale factor

IW = 12

I'W'= 8

so, solving for k:

\begin{gathered} k=\frac{I^{\prime}W^{\prime}}{IW} \\ k=\frac{8}{12}=\frac{2}{3} \end{gathered}
