Well the formula for the perimeter of a rectangle is 2w+2l
w=width
l=length
So it is 2(665)+2(421)=2172
Sally has to have emergency surgery and will need to pay extra hospital fees.
3xy
<span>y(3y)/3xy + y(xy)/3xy + (y+1)(3x)/3xy </span>
<span>NOW since all of the fractions have a denominator of 3xy, drop the denominators and solve using the numerators. </span>
<span>y(3y) + y(xy) + (y+1)(3x) </span>
<span>3y^2 + xy^2 + 3xy +3x </span>
<span>cannot simplify further.</span>
