Answer:
x = ±sqrt(2)
Step-by-step explanation:
8x^2 - 5 = 11
Add 5 to each side
8x^2 - 5+5 = 11+5
8x^2 = 16
Divide each side by 8
8x^2 = 16/8
x^2 = 2
Take the square root of each side
sqrt(x^2) = ±sqrt(2)
x = ±sqrt(2)
14.19 + 13.78 = 27.97 seconds for Ryan
15.77 + 16.24 = 32.01 seconds for Daniel
32.01 - 27.97 = 4.04 seconds greater
