Question

Write a simplified polynomial in standard form that represents the perimeter of given triangle

Answer 1

Explanation:

Perimeter of a triangle is the three sides added together:

(x + y) + (3y + 4z) + (2x - z)

Simplify:

x + y + 3y + 4z + 2x - z

Rearrange to get like terms together:

x + 2x + y + 3y + 4z - z

3x + 4y - 3z
