22 Lesson 1 Ex5 BIOLOGY There are about 5 × 10 6 red blood cells in one milliliter of blood. A certain blood sample contains 8.32 × 10 6 red blood cells. About how many milliliters of blood are in the sample? Divide the number of red blood cells in the sample by the number of red blood cells in 1 milliliter of blood. Answer: There are about 1.66 milliliters of blood in the sample. number of red blood cells in sample number of red blood cells in 1 milliliter

24 End of Lesson 1

25 Lesson 2 Ex2 Simplify Polynomials A. Simplify (2a 3 + 5a – 7) – (a 3 – 3a + 2). (2a 3 + 5a – 7) – (a 3 – 3a + 2) = a 3 + 8a – 9Combine like terms. Group like terms. Distribute the –1. Answer: a 3 + 8a – 9

26 Lesson 2 Ex2 Simplify Polynomials B. Simplify (4x 2 – 9x + 3) + (–2x 2 – 5x – 6). (4x 2 – 9x + 3) + (–2x 2 – 5x – 6) = 2x 2 – 14x – 3Combine like terms. Remove parentheses. Group like terms. Answer: 2x 2 – 14x – 3
