Question

describe the downfall of mohenjo daro
​

Answer 1

Explanation:

• ANSWER EXPLANATION: There are two ways to solve this question. The faster way is to multiply each side of the given equation by ax−2 (so you can get rid of the fraction). When you multiply each side by ax−2, you should have:
• 24x2+25x−47=(−8x−3)(ax−2)−53
• You should then multiply (−8x−3) and (ax−2) using FOIL.
• 24x2+25x−47=−8ax2−3ax+16x+6−53
• Then, reduce on the right side of the equation
• 24x2+25x−47=−8ax2−3ax+16x−47
• Since the coefficients of the x2-term have to be equal on both sides of the equation, −8a=24, or a=−3.
• The other option which is longer and more tedious is to attempt to plug in all of the answer choices for a and see which answer choice makes both sides of the equation equal. Again, this is the longer option, and

Answer 2

Explanation:

Apparently the Indus civillization was likely destroyed by the Indo-European migrants from Iran, the Aryans. The cities of Mohenjo-Daro and Harappa were built of fire-baked bricks. Over the centuries the need for wood for brick-making denuded the country side and this may have contributed to the downfall.
