Answer:

2x^3 + 5x^2 - x - 6

Step-by-step explanation:

[NOTE]

I am assuming x2 is x^2, if I am wrong about that then please notify me in the comments

[END NOTE]

The parenthesis are implications that we multiply the numbers within them.

Therefore, multiply.

(2x)(x2)

2x^3

(2x)(x)

2x^2

2x^3 + 2x^2

(2x)(-2)

-4x

2x^3+2x^2-4x

(3)(x2)

3x^2

2x^3+2x^2-4x+3x^2

(3)(x)

3x

2x^3+2x^2-4x+3x^2+3x

(3)(-2)

-6

2x^3+2x^2-4x+3x^2+3x-6

Now combine like terms, meaning the numbers with the same endings, you cannot add a number with different exponents and adding numbers with and without a variable.

2x^3 + 5x^2 - x - 6

Consider a nuclear power plant that produces 1200 MW of power and has a conversion efficiency of 34 percent (that is, for each u
Pachacha [2.7K]

Answer:

Fuel used = 111,303,473,760 MJ/year

Step-by-step explanation:

Power production = Fuel energy * Efficiency

1200 MW = Fuel energy * 0.34

Fuel energy = 1200 MW / 0.34 =3529.41 MW

This means it consumes 3529.41 MJ/s.

Per year, it operates 365 days, 24 hours a day, 3600 seconds an hour.

To calculate the fuel used annualy we have to multiplicate by all these factors

Fuel used = 3529.41 MJ/s * 3600 s/hour * 24 hours/day * 365 days/year

Fuel used = 111,303,473,760 MJ/year
