Which procedure justifies whether -3.5-4)=3(x-6) is equivalent to -12x-6?
The expressions are not equivalent because -32,5-4)=3(2-6)=-18 and -12/2)-6=-30
The expressions are not equivalent because -3(2)(5-4)+312-6)=-18 and -12[3)-6=-42
The expressions are equivalent because -3(2)(5-4)+312-6)=-18 and -12(-2)- 6= 18
The expressions are equivalent because -3125-4)+312-6)=-18 and -123-6=-18

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,

step-by-step explanation:

by good luck mark me as brainliest

have a nice day

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.
