Bella's sequence is correct; For once, we can check the scale factor. The large side in the blue shape is 8 units long, while in the red shape it is 12. Hence, the scale factor is 12/8=1.5. Also, we have that the rotation part is correct, since the rotation needs to be 180 degrees to get an upside down version of the shape.
Marco's sequence is almost correct, but due to the reflection part, the 2 shapes should have the same orientation after this procedure. Hence, we get that the pointy parts of the shapes should point to the same direction. This is clearly not the case here, so Marco's procedure is wrong; in fact, his procedure yields almost the same object as the red one, only reflected along the y-axis.
