Mark has 42 identical cubes, each with 1-cm edges. He glues them together to form a rectangular solid. If the perimeter of the base is 18 centimetres, find the height of the rectangular solid, in cm.

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.
