Sophie put up three bookshelves in her room. The top shelf is 3.88 feet long, the
middle shelf is 2.63 feet long, and the
bottom shelf is 4.56 feet long.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

its kind of blurry. can you put a clearer pic?
