1) If v= (t, 2t-1, 2t) is a unit vector, find t

- can't figure out how to solve for t. (oh and in the question there is an arrow over the v but i cant figure out how to do that on here)

2)Find a parametric equation for the plane 2x+6y-5z-30=0

-not exactly sure how to change a scalar equation into a paramteric equation
