The height of a triangle is 4 inches greater than twice its base. the area of the triangle is no more than 168 in.² which inequality can be used to find the possible lengths, x, of the base of the triangle?
a. x(x+2)=> 168
b. x(x+2)=< 168
c. 1/2x(x+4)=< 168
d. 1/2x(x+4)=> 168

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.
