A line segment has two endpoints unlike a line where a line is infinite with no end! :) Think of a line segment essentially just being two points on a line. :)
When it gets to zero or the intercept
factor
x=4(t^2-8t+9)
x=(4)(t-9)(t+1)
set to zero
t-9=0
t=9
t+1=0
t=-1, false, time cannot be negative
at t=9 seconds
To eliminate the fraction, multiply by 2 both sides of the equation. This gives,
2A = h x (b1 + b2)
Then, divide both the left hand and the right hand side of the equation by the variable h.
2A / h = b1 + b2
Next, subtract b1 from both sides,
(2A / h) - b1 = b2
Rearranging the equation,
b2 = (2A/h) - b1
