if an area of a rectangle is expressed as 3x^4-2x^2-10x-20, and the width of the same rectangle can be expressed as x-2, what is the length of this rectangle?

Iwill give brainliest. suppose tommy walks from his home at (0, 0) to the mall at (0, 5), and then walks to a movie theater at (6, 5). after leaving the theater tommy walks to the store at (6, 0) before returning home. if each grid square represents one block, how many blocks does he walk?
