Which inequality represents the values of X that insure triangle ABC exists

7/4 < x < 11/2

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My answer

Given the information:

All of these three triangle inequalities must be satisfied:

<=> 2x + 4 + 6x > 18

<=> 8x > 14

<=> x > 7/4

6x + 18 > 2x + 4

<=> 4x > -14

<=> x > -14/4

18 + 2x + 4 > 6x

<=> 22 > 4x

<=> x < 11/2

So the inequality represents the values of X that insure triangle ABC exists is:  7/4 < x < 11/2

Hope it will find you well.

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
