Edit: Nevermind. I figured out that I was using the wrong coords and the wrong mass of the second object. The correct answer was -.25m.

The formula for center of mass is

Where A is area and h is height of the object.

This is a very easy topic and a very easy question. I'm just having trouble seeing where the coords are. In my attempt I had the following values:

**<<<<<< here: x_1 = x_2 = 0** **<<<<< x_3 = -1**
My final answer was 1.54m. The online system tells me this is wrong. Does anyone see where I went wrong?

Thanks.
