Answer:

Step-by-step explanation:

When an eagle gains the height, elevation of the eagle will be positive and when it goes down elevations will be negative.

Initial height of the eagle = 42 ft

Achieves the elevation = 144 ft

Goes down to 162 ft so the elevation will be = -162 ft

Gains the height again therefore, elevation of the eagle = 25 ft

Goes down to 65 feet so the elevation = -65 ft

Therefore, expression representing the eagle's flight will be,

(42 + 144 - 162 + 25 - 65)

Elevation at the brook = (42 + 144 - 162 + 25 - 65)

                                     = 20 ft
