    Multiply n by 2 i.e. \(n \times 2 \implies 2n\) Now add 1 to what we have got : \(2n + 1\) So, your expression is : \(2n+1\) And lastly I know about sketching the area model, I have not studied that, Sorry..

    jamal works at a book store. he is putting copies of two kinds of books on a shelf. the first book has a width of exactly 2 cm. the second book has a width of exactly 2 in. jamal wants to know the combine width of x copies of the first book and y copies of the second book. [note: 1in= 2.54 cm] <- use this need help for this one

    This is not easy for me.. \(n^2\) will represent a Square with length of its side as 'n'. What we do when it is square root??

    \[x\times2[\text{cm}]+y\times2[\text{in}]\] \[=x\times2[\text{cm}]+y\times2[\text{in}]\times\frac{2.45[\text{cm}]}{[\text{in}]}\]
