Chad used a number line to show the distance from the library to his house and the distance from the library to Kelli's house. How much father is Chad's house than Kelli's house from the library?

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares

The quadratic function h(t)=-16.1t^2+150 choose the graph representation
