An equilateral triangle has a perimeter of 15x3 + 33x5 feet. What is the length of each side?
Answer
A
x3 feet
B
5 + 11x2 feet
C
5x2 + 11 feet
D
5x3 + 11x5 feet
Explanation
An equilateral triangle has three equal sides, so divide its perimeter by 3: (15x³ + 33x⁵) ÷ 3 = 5x³ + 11x⁵. Each side is 5x³ + 11x⁵ feet, which is choice D.
