To simplify the equation combine the like terms:

-2x^2 - 10x^2 = -12x^2

3-10 = -7

The simplified expression is -12x^2 + 5x - 7

-2x² + 3 + 5x - 10 - 10x²

Collect the like terms

-12x² + 3 + 5x - 10

Calculate the difference

-12x² - 7 + 5x

Use the commutative property to reorder the terms

-12 + 5x -7

I need help please help!

Answer:

50.5 m^3

Step-by-step explanation:

Volume of pyramid = 1/3 × base area × height.

  • Height: 11
  • Base Dimensions: 4.3 and 3.2

Area of Base:

  • 4.3 * 3.2
  • 13.76  

Next, we multiply 13.76 by 11.

  • 13.76 × 11
  • 151.36

Lastly, divide by 3 and round to nearest tenth.

  • 151.36 ÷ 3  
  • 50.453333..
  • ≈ 50.5

Therefore, the answer is 50.5 m^3

Assume there are 365 days in a year.
Dahasolnce [82]
The chance of student 1's birthday being individual is 365/365 or 100%.
Then the chance of student 2's birthday being different is 364/365.
Then it's narrowed down to 363/365 for student 3 and so on until you get all 10 students.
If you multiply all these values together, the probability would come out at around 0.88305182223 or 0.88.

To get all the same birthday you'd have to the chance of one birthday, 1/365 and multiply this by itself 10 times. This will produce a very tiny number. In standard form this would be 2.3827x10'-26 or in normal terms: 0.23827109210000000000000000, so very small.
