She is not wrong. 12.6 is less than 12.63
Alright first things first you need to distrubute 6(x-5) so that will be 6x-30=54
In order for you to get x by itself you need to add -30 on both sides so that'll be your second step is to add -30 on both sides: -30+-30 54+-30. Cancel out -30 and add the 54 and -30 together and you'll get 24.
Third and final step you have 6x=24 but you aren't done yet. You need to get X by it self so divide 6 on both sides. Cancel out the x and now you have x by itself. Divide 24 and 6 and you'll get 4
So your answer will be x=4.
Hope this helped :)
have a great day

Answer:
225
Step-by-step explanation:
If you move the bottom triangle up (as shown in the picture) it's not actually a square. And they haven't provided you with enough information to solve for anything unless there are still unknown values. You would need to know at least another leg length or angle. If they want the actual value in square millimeters, my best guess is that it's <em>supposed </em>to be a square. Since a square has sides of the same length, the area would be 15 * 15 which is 225.
