12-[20-2(6²/3*2²)]
=12-[20-2(36/3*4)]
=12-[20-2(12*4)]
=12-[20-2(48)]
=12-[20-96]
=12-(-76)
=12+76
=88
Use distance formula
= sqrt ( (y2-y1)^2 + (x2-x1)^2) where the 2 points are (x1,y1) and (x2,y2).
so answer is sqrt ((9-8)^2 + ((-3--6)^2) = sqrt (1 + 9) = sqrt 10
answer is sqrt 10 or 3.16 to nearest hundredth.
A.(10,-86) you would substitute this into the equation, which would be correct.
You just have to divide the number of blocks walked by the number of hours
