Suppose that the functions h and g are defined as follows.
h(x) = x+9
g(x) = (x+2)(x+5)
(a) Find (h/g) (-4).
(b) Find all values that are NOT in the domain of
h/g

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
