Answer:
13y² - 6z
Explanation:
Amount spent per month = 5y²-2z
Amount saved per month = 8y²-4z
Amount earned per month = (Amount saved per month + Amount spent per month)
Amount earned per month :
8y²-4z + 5y²-2z
8y² + 5y² - 4z - 2z
13y² - 6z
Songhai's wealth and power were derived from <em>c. the merchant crossroads and cities of the middle Niger.</em>
- Trade brought wealth to the Songhai kingdom. It also sustained its power. It enabled the king, Sonni Ali, to expand his kingdom, creating stronger armies from the wealth derived from trade.
- The Songhai's wealth was also increased because of its large territory, through which the trans-Saharan trade network passed. The kingdom was blessed with mineral mines, extensive rivers, grassland, and many natural resources.
Thus, the wealth and power of Songhai were not derived from its extensive mines, Timbuktu's reputation, or the tribute received from subjects alone. But its wealth and power flourished because of the merchant crossroads and cities of the middle Niger.
