What is the slope and y-intercept of the equation represented by the following graph

1. are the triangles similar and if so why? what is the value of x? show your work.

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 suare root of 9x plus 7 plus the square rot of 2x equall to 7
