The northbound bus arrives at the station every 15 minutes. The
southbound bus arrives at the
station every 20 minutes. If both
buses leave at the same time, how
long will it be before both buses
arrive back at the same time?

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)

If a || b and e || f , what if the value of y ?

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
