Answer:

x = 2, x = -6

Step-by-step explanation:

$x^2+4x-4=8$

Subtract 8 from both sides.

$x^2+4x-4-8=8-8$

Simplify.

$x^2+4x-12=0$

Solve with quadratic formula.

a = 1

b = 4

c = -12

I do not have time to show work for quadratic formula parts.

I am so sorry for this inconvenience.

We have no clue because you have not said what the speed/pace is. At a speed of 17.23 mph you will bike 112miles in 6.5 hours.
