Practice Question
Which of the following must be true?
Answer Choices
- A: 4x-3=26
- B: 4x-1=26
- C: 5x-1=26
- D: 5x+1=26
Correct Answer: A
Rationale: Small base = x cm. Large base = 2x - 3 cm. Legs = x + 2 cm. Perimeter = x + (2x - 3) + 2(x + 2) = x + 2x - 3 + 2x + 4 = 5x + 1 = 26. Thus, the correct answer is 4x-3=26.
