two towns have different elevations but when the elevations are used as inputs of 'f(x)' they both produce an input of 25. what are their elevations?

The table above shows approximate conversions from gallons to liters. what is the value of 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?
