The given expression is \((x - 5)(x + 7)\), and we need to find which of the provided options is equivalent to it.

We will expand the expression using the distributive property (also known as FOIL in this case):

\[
(x - 5)(x + 7) = x(x + 7) - 5(x + 7)
\]

Expanding both terms:

\[
x(x + 7) = x^2 + 7x
\]
\[
-5(x + 7) = -5x - 35
\]

Now, combine the like terms:

\[
x^2 + 7x - 5x - 35 = x^2 + 2x - 35
\]

Thus, the equivalent expression is:

\[
x^2 + 2x - 35
\]

The correct answer is **A**: \(x^2 + 2x - 35\).
