Brian is solving the equation 2x-3/4x=5 what value must be added to both sides of the equation to make the left side a perfect-square trinomial?

Step by step solution

Multiplying each term with we get

Splitting the above expression in the form of

where

adding and subtracting

to the above polynomial..

the diameter is 16 cm. are you a teacher?

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.
