Hank’s teacher asked him to verify that the product (y – 3)(y2 + 3y + 9) is a difference of cubes. He used the distributive prop
erty to multiply the binomial times the trinomial. Before simplifying, his product was a polynomial of the form y3 + 3y2 + ay – 3y2 – ay – 27. What is the value of a in the polynomial?
The unknown is the distance in kilometres The given is the distance in miles=140 miles 1 mile=1.6093km 140 miles=? 140/1*1.6093km=225.302km Therefore the 140 miles in km is 225.302km
