This document contains notes from a math lesson, including assignments that are due, information about a test, and examples of finding the area of irregular polygons by dividing them into smaller shapes. It provides warm-up problems on factoring, solving equations, and setting up a customer-teller ratio. The lesson content explains how to calculate the area of irregular figures by dividing them into polygons. Examples are given to find the area of three irregular polygons broken into triangles and rectangles.
