Two-variable equations as models
example: miranda has 55 feet of fencing. she wants to use all the fencing to
create a rectangular garden. the equation 21 + 2w = 55, where t is the length of
the garden and w is the width, models the scenario. this equation can be used to
find one dimension of the garden if the other dimension is known.
think about constraints:
each side must be
than 0.
each side must be
then 27.5.
each side must be greater than a
inches.
