Find the greatest common factor of 20b and 12a^2

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.

Predict which statements are true about the intervals of the continuous function. check all that apply

Hello, i need compare km^2 and km. what's difference in this?
