and their sum as =-3 ... please slov e the further qstn..

Answer 1

Let the numbers be ( a - d ) , a , ( a + d ).

Given,

⇒Sum of the terms = -3

⇒( a - d ) + a + ( a + d ) = -3

⇒a - d + a + a + d = -3

⇒3a = -3

⇒ a = ( -3 ) ÷3

•°• a = -1

Now,

⇒Product of numbers = 8

⇒ ( a - d ) ( a + d ) a = 8

Using identity,

⇒ ( x + y ) ( x - y ) = x² - y²

⇒ ( a² - d² ) a = 8

Substituting the value of ( a = -1 ),

⇒ [ ( -1 )² - d² ] ( -1 ) = 8

⇒ [ 1 - d² ] ( -1 ) = 8

⇒ -1 + d² = 8

⇒ d² = 8 + 1

⇒ d² = 9

⇒ d = √9

•°• d = 3

Now,

Numbers = ( a - d ) , ( a ) , ( a + d )

= [ ( -1 ) - 3 ] , ( -1 ) , [ ( -1 ) + 3 ]

= ( -1 - 3 ) , ( -1 ) , ( -1 + 3 )

= ( -4 ) , ( -1 ) , ( 2 )

Hence, the numbers are -4 , -1 and 2.

Answer 2

Answer:

The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe.
