Which expression is equivalent to (3x² + 3x - 3) - (6x² - 4x - 2)?
Marat540 [252]

Answer:

A. 12x^{4} -4x^{3} +3x^{2} +3x+20

Step-by-step explanation:

For this problem, we have to combine like terms.

Let's look at the equation:

(12x^{4} -4x^{3} +7x+6)+(3x^{2} -4x+14)

12x^{4, -4x^{3}, 3x^{2} do not have any other like terms, so we keep all in the final answer.

7x and -4x are like terms, so we combine them. 7x-4x=3x

14 and 6 are like terms, so we combine them. 14+6 = 20

Let's put everything into the final equation:

12x^{4} -4x^{3} +3x^{2} +3x+20

So, the final answer is A. 12x^{4} -4x^{3} +3x^{2} +3x+20

Hope this helps! If you have any questions about my work, leave them in the comments below!

How long does it take for a deposit of $900 to double at 2% compounded continuously?
nydimaria [60]

9514 1404 393

Answer:

  • 34.6574 years
  • 34 years, 239.94 days

Step-by-step explanation:

For continuous compounding the "rule of 69" applies. That is the doubling time can be found from ...

  t = 69.3147/r . . . . where r is the interest rate in percent.

Here, r=2, so ...

  t = 69.3147/2 = 34.6574 . . . years

That's 34 years and 240 days.
