What is the solution to the equation represented by the model below? x = negative 14
x = negative 2
x = 2
x = 14

2x + 4

To model 2x+4, you need :

2 positive x-tiles to represent 2x.

4 positive unit tiles to represent 4.

3x+(-1)

To model 3x+(-1), you need :

3 positive x-tiles to represent 3x.

1 negative unit tile to represent (-1).

if its wrong sorry u can report me

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.
