Answer 1

Answer:

1.$\boxed{-7x2-6x}$

Step-by-step explanation:

1. Multiply the numbers

• ( 7 ⋅ 2 − 6x  − 3 ) − 1 ( 7x ^ 2 + 1 1 )
• ( 1 4 − 6x  − 3 ) − 1 ( 7x^  2 + 1 1 )

  2. Subtract the numbers

• ( 1 4 − 6x  − 3 ) − 1 ( 7 x^ 2 + 1 1 )
• ( 1 1 − 6x  ) − 1 ( 7  2 + 1 1 )

   3 Rearrange terms

• ( 1 1 − 6x  ) − 1 ( 7 x^2 + 1 1 )
• ( − 6x  + 1 1 ) − 1 ( 7x^  2 + 1 1 )

   4 Distribute

• ( − 6x  + 1 1 ) − 1 ( 7x^  2 + 1 1 )
• ( − 6x  + 1 1 ) − 7  2 − 1 1 5

   5.Eliminate redundant parentheses

• ( − 6x  + 1 1 ) − 7X^ 2 − 1 1
• − x6  + 1 1 − 7  2 − 1 1 6

   7. Subtract the numbers

• − 6x  + 1 1 − 7x  2 − 1 1
• − 6x  − x7  2 7

   8.Rearrange terms

• − 6x  − 7  2
• − 7x  2 − 6

1. Volume of a cylinder 9 radius and 15 height

• V≈3817.04
