Practice Question
The width of a painting is 24 centimeters shorter than its length, x. The area of the painting is 4,081 square centimeters. Which equation could be used to find the dimensions of the painting?
Answer Choices
- A: x^2 - 24x - 4,081 = 0
- B: x^2 + 24x - 4,081 = 0
- C: x^2 + 24x + 4,081 = 0
- D: x^2 - 24x + 4,081 = 0
Correct Answer: A
Rationale: Width = x - 24, area = x(x - 24) = 4081. Thus, x^2 - 24x - 4081 = 0. Thus, the correct answer is x^2 - 24x - 4,081 = 0.
