<h2><em><u>EXPLANATION :-</u></em></h2>

= (2 {n}^{2} - 5n - 6) + (  - {n}^{2} - 3n  + 11)

= 2 {n}^{2}  - 5n - 6 -  {n}^{2} - 3n  + 11

= 2 {n}^{2} -  {n}^{2}  - 5n - 3n - 6 + 11

= (n²-8n+5)→Answer

I hope that it answer your question...

Adding the tax?
 
to add taxes it requires only two steps:
1) multiply the price by the tax as a Decimal (tax must be in decimal form)
2) add what you get after multiplying to the original price
 So..
1) 49.95(.05) = 2.497
 
2) 49.95+ 2.497 = 52.447 round to 52.45

So the whole price is $52.45

**you can also round the 49.95 to 50 before doing the math to make it easier**

A polynomial P has non-negative integer coefficients. If P(1) = 8 and P(10) = 2312, what is P(2)?​
polet [3.4K]

9514 1404 393

Answer:

  32

Step-by-step explanation:

If coefficients are positive integers, then the polynomial cannot be higher degree than 3. 10^4 = 10,000, so even a coefficient of 1 will give too large a value. P(1) = 8 tells us that the sum of coefficients must be 8, so we cannot have a degree lower than 3.

The sum of digits in 2312 is 8, so it works out that the polynomial is ...

  P(x) = 2x^3 +3x^2 +x +2 . . . . matches P(1) = 8 and P(10) = 2312

Then P(2) is ...

  P(2) = ((2·2 +3)2 +1)2 +2

  P(2) = 32
