What is the correct answer for3(x-1) -8=4(1+x)+5

First to figure out the problem you need to distribute the 3 and the 4. You get, 3x-3-8=4+4x+5. Now you need to combine the coefficients. After doing this you will have 3x-11=9+4x. Now to get x by itself you need to subtract 3x from both sides. You will have -11=9+x. Then you subtract 9 from both sides and you end up with x=-20

3(x-1)-8=4(1+x)+5

3x-3-8= 4+4x+5

3x-11=9+4x

-3x        -3x

-11=9+x

-9   -9

-20=x

where are the choices?

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.
