provided that you submit the quiz no later than the due date posted in our course schedule

 

of the syllabus. You may refer to your textbook, notes, and online classroom materials,

require work, write a sentence or two to justify your answer.

containing your work. Scanned work is also acceptable. Be sure to include your name in

 

the document.

work to show, then include a sentence or two explaining your answer.

a) Each step should show the complete expression or equation rather than a piece of it.

 

b) Each new step should follow logically from the previous step, following rules of algebra.
