Answer:
The length is 6 meters.
Step-by-step explanation:
If its width is x meters then its length is 2x + 2 meters and we have the equation:
2x + 2(2x + 2) = 16
2x + 4x + 4 = 16
6x = 16 - 4
6x = 12
x = 2 meters.
Thus x is the width and the length is 2(2) + 2 = 6 meters.
The nonzero vector orthogonal to the plane is <-9,-8,2>.
Consider the given points are P=(0,0,1), Q=(−2,3,4), R=(−2,2,0).
The nonzero vector orthogonal to the plane through the points P,Q, and R is
Expand along row 1.
Therefore, the nonzero vector orthogonal to the plane is <-9,-8,2>.

In ten minutes she walked 1-0.5=0.5 miles.
60 minutes/10 minutes=6. So 0.5 miles ×6=3 miles per hour
