Anais decided to make her rectangular outdoor
swimming pool larger so she can invite more people
over for pool parties. The pool’s original length was 14
feet and the width was 10 feet. She increases the length
and width by the same amount.
Part A Express the area of the new swimming pool
as a polynomial in simplest form.
