Question

the length of a rectangle is 3 inches more than its width.

Write an equation for the situation above by multiplying the factors together and setting the equation equal to zero

Answer 1

perhaps you know the area as well?

Answer 2

sorry;{ 180=(w+3)(w)

Answer 3

ah from before
then
\[w^2+3w=180\]
\[w^2+3w-180=0\]
\[(w+12)(w-15)=0\] so
\[w=15\] because -12 makes no sense in this problem
