An equilateral triangle has a perimeter of 15x^3 + 33x^5 feet. What is the length of each side?

5x^3 + 11x^5  ft

Step-by-step explanation:

An equilateral triangle has all three sides of equal length, so the perimeter is found  by

P =3s  where s is the side

We know the perimeter

15x^3 + 33x^5 = 3s

Divide each side by 3

15/3x^3 + 33/3x^5 = 3/3s

5x^3 + 11x^5 = s

Each side is 5x^3 + 11x^5  ft

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
