What are the factors of x2 – 100? (x – 50)(x 50) (x – 10)(x 10) (x – 25)(x 4) (x – 5)(x 20).

Layer r contains a well-known index fossil that is 100 million years old. based on this information and the principle of superposition, a. layers t and m are older than 100 million years, and layers x and g are younger than 100 million years. b. layers t, m, x, and g are all older than 100 million years. c. layers t and m are younger than 100 million years, and layers x and g are older than 100 million years.
