On the left side of the scale:

There are 2 triangles, each with weight x.
There are 6 circles, each with weight 2.
On the right side of the scale:

There are 4 triangles, each with weight x.
There are 2 circles, each with weight 2.
To represent a balanced hanger, the weights on both sides of the scale should be equal. Based on this, the correct equation would be:

D. 2x + 12 = 4x + 4

On the left side of the equation, we have...
