|dw:1442767434290:dw| all sides have equal length

2. pooja195

So x=25? Since all sides have equal length??

3. Nnesha

|dw:1442767516811:dw| they are asking what's x not the length of AB

4. pooja195

lol they are asking for the value of x :/

5. Nnesha

or you can do backwards substitute x for one of the answer choices plug in 7x-3 where x is you should get 25

$$\color{#0cbb34}{\text{Originally Posted by}}$$ @pooja195 So x=25? Since all sides have equal length?? $$\color{#0cbb34}{\text{End of Quote}}$$ So then this was right???

7. Nnesha

let's substitute x for 25 $7(25)-3= 25$ both sides are equal if no then 25 is incorrect

8. pooja195

thats incorrect ._.

9. Nnesha

yes right |dw:1442767717175:dw|AB = DC AB= 7x-3 DC=25 so replace AB with 7x -3 and DC with 25 then solve for x
