Yes, the link was blocked in my computer. I used a different computer to see it.

\(|k + 9| = 4\)

To solve an absolute value equation like yours, set up two equations. In one, set the inside of the absolute value equal to the number and the other, set the inside of the absolute value equal to the negative of the number.

\(k + 9 = 4\) or \(k + 9 = -4\)

Now solve both equations and keep the word "or" in between the solutions.
In both equations, subtract 9 from both sides.

\(k = -5\) or \(k = -13\)

The correct choice is A.
