1. Irrigation provided Mesopotamian civilization with the ability to stretch the river's waters into farm lands. This led to engineering advances like the construction of canals, dams, reservoirs, drains and aqueducts. One of the prime duties of the king was to maintain these essential waterways.

2. However, there were three disadvantages to their new environment. Unpredictable flooding combined with a period of little or no rain. The land sometimes became almost a desert. With no natural barriers for protection, a Sumerian village was nearly defenseless.

3.The need for order, structure, and unity through large areas of land led to the beginnings of organized government in Sumer.

4. Pyramids were built for religious purposes. The Egyptians were one of the first civilizations to believe in an afterlife. They believed that a second self called the ka lived within every human being. ... Three pyramids were built at Giza, and many smaller pyramids were constructed around the Nile Valley.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
