Write an expression for the area of the pool, if the radius is 5p-3m

Hi Makayla;

area=pi(r

^{2})This is actually an equation, not expression. An expression does not have the = sign.

area=pi(5p-3m)

^{2}We can expand the parenthetical equation.

Let's FOIL (5p-3m)(5p-3m)

FIRST...(5p)(5p)=25p

^{2}OUTER...(5p)(-3m)=-15pm

INNER...(-3m)(5p)=-15pm

LAST...(-3m)(-3m)=9m

25p

^{2}-30pm+9marea=pi(25p

^{2}-30pm+9m)
