Answer:

A = 48

Step-by-step explanation:

In this equation, we can factor out the expression [tex](\frac{1}{7} )^x[/tex]. If we do so, the expression becomes:

[tex](\frac{1}{7})^x((\frac{1}{7})^{-2} - 1)[/tex]

We can simplify to get:

[tex](\frac{1}{7} )^x(49 - 1)[/tex]

and get:

[tex]48*(\frac{1}{7})^x[/tex]

Therefore, A = 48
