Thank you for posting your question here in brainly. The answer to the above equation is letter C which is x + 9 remainder –9. Please see below solution:

x2 + 17x + 63 / x + 8 = x + 9 r-9
x2 + 8x
9x + 63
9x + 72
-9

Answer:

Step-by-step explanation:

I did the division process in the picture below. The result can be viewed as

$\frac{x^2+17x+63}{x+8} = (x+9)(x+8) -9$ . Then, the result is x+9 and the remainder is -9.

Please, do not post more than 1 or 2 questions at a time. Out of courtesy I will address one of your six questions here:

2x + 4 = 3(x – 2) + 1

You are to solve this for x.

1) perform the multiplication: 2x + 4 = 3x - 6 + 1
2) combine like terms: 4+6-1 = x
3) solve for x: x = 11
4) check: Is 2(11) + 4 = 3(11-2) + 1 true?
Is 22+4 = 33-6 true? NO. Try again, looking for the mistake:

2x + 4 = 3(x – 2) + 1 => 2x + 4 = 3x - 6 + 1
4 = x - 5
9 = x

Check: Is 2(9) + 4 = 3(9-2) + 1 true? Is 18+4 = 22 true? YES.
The solution to #1 is x = 9 (answer).

Submit your other questions separately, please.

4x + 8y=20 3x+6y=15 solve this system of equations

laila [671]

4x=20-8y

x=5-2y now use this value of x in the second equation...

3(5-2y)+6y=15

15-6y+6y=15

15=15 This is true for any y or x value.

So there are infinitely many solutions as the two equations describe the same line.

8. The Last Supper

The number of possible seats is an illustration of permutation

There are 1728 possible sitting arrangements

<h3>How to determine the number of seats</h3>

From the question, we have the following highlights:

Chris can only take 1 seat (i.e. the central seat)
Jo can take 2 seats (i.e. the seats adjacent the central seat)
Alex, Barb and Dave can take 3! number of seats
Eddie, Fred, and Gareth can take 3! number of seats on the right of Chris.
The remaining 4 adults do not have preference, then they can seat in 4! ways

So, the number of sitting arrangement is:

$n = 1 * 2 * 3! * 3! * 4!$

Evaluate the product

$n = 1728$

Hence, there are 1728 possible sitting arrangements
