Answer:
5
Step-by-step explanation:
5 > 0 (True)
Plug in 5 for t in the equation.
t² - 25 = 0
(5)² - 25 = 0
(5 * 5) - 25 = 0
(25) - 25 = 0
0 = 0 (true).
~
t =5
t^2 - 25 = 0
Add 25 to each side
t^2 - 25 +25= 0+25
t^2 = 25
Take the square root of each side
sqrt(t^2) = sqrt(25)
t = ±5
t >0 so t must be 5
