Add together all of the quadratic equations below which have two real number solutions:

1. $${ 2x }^{ 2 }+4x-2$$
2. $${ x }^{ 2 }+9x+16$$
3. $$-{ x }^{ 2 }+x-10$$
4. $${ x }^{ 2 }+13x+42$$
5. $${ 9x }^{ 2 }+60x+1$$
6. $${ 16x }^{ 2 }+32x+31$$
7. $${ 2x }^{ 2 }+5x-22$$
8. $${ -14x }^{ 2 }-28x-10$$
9. $${ 2x }^{ 2 }+20x+100$$
10. $${ 30x }^{ 2 }+90x+90$$

If the sum of the quadratic equations equals $${ Ax }^{ 2 }+Bx+C$$, find A+B+C.
