Compare Quantity A and Quantity B.
Column A: The perimeter of a square with area 25. Column B: The area of a square with perimeter 20.
For Column A, find the side length from the area, then find the perimeter. For Column B, find the side length from the perimeter, then find the area.
Show hint
Correct!
Wrong!
Compare Quantity A and Quantity B.
Given: x > 1. Column A: 1/x. Column B: 1/(x+1).
Since x > 1, both x and x+1 are positive. When comparing positive fractions with the same numerator, the one with the smaller denominator is larger.
Show hint
Correct!
Wrong!
Compare Quantity A and Quantity B.
Line L passes through points (1,2) and (3,6). Column A: The slope of Line L. Column B: 2.
Slope = (y2 - y1) / (x2 - x1).
Show hint
Correct!
Wrong!
Compare Quantity A and Quantity B.
Given: a and b are integers. ab = 12. Column A: a+b. Column B: 7.
Consider different integer pairs (a,b) whose product is 12 (e.g., 1&12, 2&6, 3&4, -1&-12).
Show hint
Correct!
Wrong!
Compare Quantity A and Quantity B.
