74 units would be your answer for the length segment
I believe its 27 cause u have to multiply 3 times 3 which is 9, then 3 times 9 which is 27
2/5 at the top nd bottom, but 0/5 on the sides. So 2/5 + 0/5= 1/5
<span>To do that, you need to set it all to zero and factor:
x^2+8x+15 = 0
(x+5)(x+3) = 0
then put both those in parentheses chunks in their own equations
x + 5 = 0
x + 3 = 0
and then simplify
x = -5
x = -3
So the two points where the parabola crosses the x-axis are -5 and -3.</span>
