Tom compared 2/12 and 7/6 by first comparing each fraction to 1/2 and 1. Step 1: 2/12 is less than 1/2. Step 2: 7/6 is less than 1 but more than 1/2. Step 3: So, 2/12 < 7/6 In which step did Tom mess up?

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

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?
