Solve the equation 7+2 |2x+1| =15

I believe the answer is X=2.5

Step-by-step explanation:

7+2=9

so now we have to find what X would be so we can do the second equation

So we know that the second equation must equal 6 because 9+6=15

So now we experiment with different numbers for X

if we did 2, the new equation would be 2x2+1 which is 5, too low

if we did 3, the new equation would be 2x3+1 which is 7, too high

So we need something in the middle

in the middle of 5 and 7 is 6 which is the number we need

so to get 6 we need something in between 2 and 3, which in 2.5

hope this helped!

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.
