The two quantities are equal. ŠŠThe relationship cannot be determined from the information given. ŠŠA ŠŠBecause the values for A and B are numbers, you know immediately that answer choice D is not correct. You can compute A and B to see the relationship. 62 ŠŠŠŠŠŠ Thus, A b B. The correct answer is choice A. ŠŠB ŠŠSolve the equations to find the sum of the solutions, or use the fact that if ŠŠŠŠŠŠ ax 2 + bx + c = 0, then the sum of the solutions is . ŠŠŠŠŠŠ A: x 2 蜢 3x 蜢 10 = 0; (x 蜢 5)(x + 2) = 0; x = 5, x =蜢2; 5 + (蜢2) = 3, or .
In this case, Quantity A is greater than Quantity B. However, there is no guarantee that the rectangle is a square, and you must investigate other pairs of numbers that add up to 30 as possible measures for the length and width. If the length is 10 m and the width is 20 m, the area of the rectangle is 200 m2 , and the two Quantities are equal. If the length is 29 m and the width is 1 m, the area of the rectangle is 29 m2 , and Quantity B is greater. Therefore, the relationship cannot be determined from the given information, and the correct answer is choice D.
In Example 1, as long as you use whole numbers greater than 1, A is always greater than B. However, if , then , and B is greater. If n =蜢2, then , and B is greater. If n = 1, then , and A = B. Thus, choosing values of n only b 1 does not give a full picture of the relationship between A and B and will lead you to answer the question incorrectly. ŠŠIf the problem includes a figure (either provided for you or described in the question), try to visualize parts of the figure that are variable while the given information is still true.
