Correct answer: B (parsed from the explanation — this source omits an answer key for this item)
Explanation
Choice B is correct. Multiplying the left- and right-hand sides of the given 2= equation by 25 yields x 900. Taking the square root of the left- and right-hand = =- sides of this equation yields x 30 or x 30. Of these two solutions, only 30 is given as a choice. 2= Choice A is incorrect. This is a solution to the equation x 36. Choice C is incorrect and may result from conceptual or calculation errors.
