Number System

Much of this topic, we already know so the I Already Know section functions as notes here.
We will be using what we know about how the distributive property works as well as how to multiply positive and negative numbers. We learned how to write a verbal expression of each algebraic expression: -2(x + 4) the opposite of two groups of x plus four Answer: -2x - 4 -3(x – 6) the opposite of three groups of x minus six Answer: -3x + 18 The video provided us with examples in the first 6 minutes directly related to this topic. We worked select problems from this worksheet, #2, 6, 7, 10, 13, 15 Then we practiced expanding and then simplifying these problems:1) 2(x – 8) 2) -5(x + 9) 3) -3(x – (-3)) 4) -6(-2x + 5) 5) -3(-2x – 4)
