Question

If t>0 and t^2-25=0 what is the value of t?

Answer 1

Answer:

t =5

Step-by-step explanation:

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

Answer 2

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).
