1) The document outlines assignments due for a math class, including an odds worksheet due on Tuesday and Test #6 on Friday, with the possibility of extra credit on Test #5. 2) It provides a warm-up worksheet with 5 problems simplifying expressions and finding prime factorizations. 3) Key formulas and terms are defined for circles, including radius, diameter, circumference, pi, and the circumference formula. Examples applying these concepts are worked through.

2. Lesson 39 Warm­Up:
1) Simplify: (­3)(­5)(­2)
2) Simplify: (­2) + (­3) ­ (­4) + (­5)(­2)
3) Write the prime factorization of 77,000 using exponents.
4) Collect like terms: 5x ­ x + 2y ­ y
5) Collect like terms: 6ab ­ 5a ­ ab + b + 3a ­ 4b

3. Lesson 39
*radius – the distance from the center of a circle to a point
on the circle [radii]
*diameter – the distance across a circle measured through
its center
*circumference – the distance around a circle
*pi – 3.14 or 22 or
7
*Formula for Circumference:
"pi times diameter"
