Assuming that you invest $13,000 in the United States, how long (to the nearest year) must you wait before your investment is worth $19,000 if the interest is compounded annually? Please help! I have been stuck on this forever :(

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?
