-√20 * 15 = -15\sqrt{20} which is not rational. Square root of 20 is irrational, so a coefficient of -15 wont make it rational

Alecsey [184]

Answer:

Technician A

Explanation:

While technician B is only partially correct, the statement of the technician A is completely true. Most shops use a spray wash cabinet, which is similar to a dishwasher that contains a strong soap and hot water solution. The solution is sprayed at parts, that are placed on a turntable, under high pressure, successfully removing oil, grease, and dirt.

As the technician B stated, some shops dip major engine parts in a hot caustic solution (but not a cold one). This method is called hot tanking, and although it cleans the engine parts well, it rarely removes all of the rust and oil paint. Due to environmental issues, this method is being used less and less.
