Identify the four social groups in ancient egypt and explain who belong to each group

The social groups in ancient Egypt were pharaoh, vizier, high priests and nobles.

Pharaoh were the kings of ancient Egypt. In Egyptian civilization, the pharaohs were considered living gods. The Egyptians believed that these rulers were direct children of the god Osiris, so they acted as intermediaries between the gods and the Egyptian population.

Vizier was Pharaoh's prime minister and assisted him in managing many kingdom affairs. He had the job of transmitting the king's orders, collecting taxes, administering justice, controlling the state of public works, and also controlling river transport.

High Priests in the social hierarchy below only in Pharaoh. Endued with enormous prestige and power, they were the Priests or responsible for religion and various functions in the administration of the Egyptian Empire. They were considered the wise men of Egypt.

Nobles  the third class was intended for the nobles. Among them military chiefs, who were responsible for the security of Egyptian territory.

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -

thus the positive value for x is x = 7
