What could be the value of x in the following equation? Select all that apply.

The possible values of x for the equation you provided are -√49, -7, and √49.

Here’s a breakdown:

1. √49 equals 7, so x can be 7.
2. -√49 equals -7, so x can also be -7.
3. The values of -7 and 7 derived from the square root give us both possibilities since squaring either of these will return 49.

Thus, x could be -7 or 7, taking into account the square root principle where both the positive and negative roots are applicable.
