To solve the equation \( \sqrt{2x} + 13 = 27 \), we first isolate the square root on one side:

\[ \sqrt{2x} = 27 - 13 \]

\[ \sqrt{2x} = 14 \]

Next, we square both sides to eliminate the square root:

\[ 2x = 14^2 \]

\[ 2x = 196 \]

Now, we solve for \( x \) by dividing both sides by 2:

\[ x = \frac{196}{2} = 98 \]

Now we check if any of the provided options (25, 9, 49, 16) make the equation true:

  1. \( x = 25 \): \[ \sqrt{2(25)} + 13 = \sqrt{50} + 13 \neq 27 \]

  2. \( x = 9 \): \[ \sqrt{2(9)} + 13 = \sqrt{18} + 13 \neq 27 \]

  3. \( x = 49 \): \[ \sqrt{2(49)} + 13 = \sqrt{98} + 13 \neq 27 \]

  4. \( x = 16 \): \[ \sqrt{2(16)} + 13 = \sqrt{32} + 13 \neq 27 \]

None of the provided values make the equation true. The correct value of \( x \) that satisfies the equation is 98, which is not among the options listed.
