# Chapter 5 - Section 5.3 - Polynomials and Polynomial Functions - Exercise Set: 110

$z^{3}+2z^{2}-2z+3$ units

#### Work Step by Step

We know that the perimeter of a triangle is equal to the sum of the length of its sides. Therefore, we can add the three given sides in order to find the perimeter of this triangle. $(z+2)+(2z^{2}+z)+(z^{3}-4z+1)$ Next, we can combine like terms to simplify. $z^{3}+2z^{2}+(z+z-4z)+(2+1)=z^{3}+2z^{2}-2z+3$ units
