Answer:

2,520

Explanation:

The word ALGEBRA has 7 letters with the letter A repeated twice.

Hence we permute all 7 letters with A repeated twice

₇P₇ / 2! = 7!/ [  (2!) ( 7-7)!]

= 2,520

algol13

Explanation:

The Abbasid caliphs established the city of Baghdad in 762 CE. It became a center of learning and the hub of what is known as the Golden Age of Islam.

The Islamic Golden Age refers to a period in the history of Islam, traditionally dated from the 8th century to the 13th century, during which much of the historically Islamic world was ruled by various caliphates and science, economic development, and cultural works flourished. This period is traditionally understood to have begun during the reign of the Abbasid caliph Harun al-Rashid (786–809) with the inauguration of the House of Wisdom in Baghdad, where scholars from various parts of the world with different cultural backgrounds were mandated to gather and translate all of the world’s classical knowledge into the Arabic language.

What are ways that we can express culture through our bodies? list 3 examples​
Svetach [21]

Answer:

Explanation:

Answer:

Reorder the terms:

8 + 6p + -4p = 3(p + 4)

Combine like terms: 6p + -4p = 2p

8 + 2p = 3(p + 4)

Reorder the terms:

8 + 2p = 3(4 + p)

8 + 2p = (4 * 3 + p * 3)

8 + 2p = (12 + 3p)

Solving

8 + 2p = 12 + 3p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-3p' to each side of the equation.

8 + 2p + -3p = 12 + 3p + -3p

Combine like terms: 2p + -3p = -1p

8 + -1p = 12 + 3p + -3p

Combine like terms: 3p + -3p = 0

8 + -1p = 12 + 0

8 + -1p = 12

Add '-8' to each side of the equation.

8 + -8 + -1p = 12 + -8

Combine like terms: 8 + -8 = 0

0 + -1p = 12 + -8

-1p = 12 + -8
