A
you have to solve x^2+x-5=0
So x=(-1 +/- sqrt(1^2+4*1*5))/2
x=(-1 +/- sqrt(21))/2
1. 11 between x and 0 between y
2. 0 between x and 12 between y
3. 3 between x and 0 between y
4. 0 between x and 11 between y
5. 0 between x and 6 between y
6. (4,-2) and (-6,-2)
7. (2,12) and (2,-4)
8. (-7,-2) and (-7,-8)
9. (4,5) and (4,-7)
10. (9,9) and (-11,9)
11. (4,2) and (-10,2)
12. 4 units
13. 7 units
Hope this helps!
