How do I cite a book when writing in APA format?
APA format follows these rules Author, A. A. (Year of publication). Title of work: Capital letter also for subtitle. Publisher Name. DOI (if available) As an example: Stone, F. (2013). Alexander the Great: A life in legend. Yale University Press. Don't forget that when citing a book on a reference page, the citation must use a hanging paragraph format and be in alphabetical order relative to any other citations.
Find x in the problem 2(x+4)
When dealing with parenthesis, we must remember that we have to distribute across the whole problem. We have to distribute our 2 across x+4. We have to do this because of our order of operations or PEMDAS. Distributing our 2 we get 2*x+(2*4) which equals 2x+8. The solution to our problem is 2x+8.
Find x 2x+5=x+8
First, to find x you will need to get x on one side of the equation by itself. But remember, we need to keep our equation balanced so whatever we do to one side of the equation, we must do to the other side as well. Start by subtracting 5 from both sides. This gives us 2x=x+3. Then subtract an x from each side as well. We then get x=3. This is the solution to our problem. x=3
