The first one is A. And Sowy but meh don't know the second one...
The answer is 3√5. You use the distance formula: √((x2-x1)^2+(y2-y1)^2)
Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7
