Kyle is solving the given equation by completing the square. For the first step, he subtracts 1 from both sides of the equation. Which step
should he do next?

A) divide only 3x^2 by 3
B) Divide only -5 by 3
C) Square both sides of the equation
D) Divide each term in the equation by 3

one that is bigger than 3 1/2

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.
