One of the Ways of Thinking for this course is

**justifying**. This is how you think when you support conclusions with valid reasoning, such as with an algebraic property. For example, when you want to convince someone that 8*x*+ (2*x*− 3) is equivalent to (8*x*+ 2*x*) − 3, you can support your claim with the Associative Property of Addition.Determine if the following statements are true or false. If true,

**justify**your conclusion by stating the appropriate algebraic property. If false, explain how you know. 2-59a HW eTool (CPM), 2-59b HW eTool (CPM) and 2-59c HW eTool (CPM). Homework Help ✎(8751)(38190) = (38190)(8751)
