Mr. Smyth uses the function L(x)= 2x^2 to determine the length, in feet, of his landscaping projects. He uses the function W(x) = 5x-2 to determine the width, in feet, of each project. Which function could Mr. Smyth use to determine the price, P(x), for a rectangular project if he charges $20 per square foot?

answer: 2/4

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
