Question

find the perimeter. simplify your answer.
2z - 9, 9z - 7, 2z - 9, 9z + 3

Explanation:

Step1: Identify all sides

Sides: \(2z - 9\), \(9z - 7\), \(2z - 9\), \(9z + 3\)

Step2: Sum the sides

\((2z - 9) + (9z - 7) + (2z - 9) + (9z + 3)\)

Step3: Combine like terms

\((2z + 9z + 2z + 9z) + (-9 -7 -9 +3) = 22z -16\)

Answer:

22z - 16
