My answer is 21.

First i just tried some random numbers just to start off. I thought that the circle could be 4, so i tried it on the bottom line. So i did 4+4+4=12(as there was 3 circles) and then i gavered that the square would be 8. Next i went onto the next line up. As i knew that the triangle was 4 I had to do 4+4+4=12. Then I knew that the triangle would be 6. Then I went to the next line up. I knew that the square was 8 so i had to do 8+8=16and there was 14 left, I then halved 14 which is 7 so the hexagon must =7. I knew that 2 squares =16 and two triangles are 12 and that = 28. Then I added up the 2 circles=8 and 1 hexagon=7 and 1 triangle=6 and so my answer was 21.
