Question 858088
A book has a length of (b+2) inches and with a width of b inches. Write a simplified expression for the perimeter of the book.

-------------------------------------------------------------------------------------------------------------------------



{{{P = 2*(L+W)}}}



{{{P = 2*(b+2+b)}}}



{{{P = 2*(2b+2)}}}



{{{P = 4b+4}}}



-------------------------------------------------------------------------------------------------------------------------



The simplified expression for the perimeter is {{{4b+4}}}
