Quantitative Comparison Practice Test 3

Concept:The equation $x^2=144$ has two possible values for $x$, so compare both cases with Column B.Explanation:Given: $x^2=144$.Taking square roots gives $x=\pm 12$.Case 1: If $x=12$, then Column A $=12$, which equals Column B $=12$.Case 2: If $x=-12$, then Column A $=-12$, which is less than Column B $=12$.Since Column A can be equal to or less than Column B, the relationship cannot be determined with certainty.Answer:The relationship cannot be determined from the information given.
