2n+1, 2n+3 - consecutive odd integers

(2n+1)(2n+3)=3(2n+1+2n+3)+6\\
4n^2+6n+2n+3=3(4n+4)+6\\
4n^2+8n+3=12n+12+6\\
4n^2-4n+15=0\\
\Delta=(-4)^2-4\cdot4\cdot15=16-240=-224\\

\Delta

It's not possible.

I don't think it is.

If the first integer is 'x', then the second one is (x+2).
Their product is (x²+2x), and their sum is (2x+2).

You have said that  (x²+2x) = 3(2x+2) + 6

                                 x²+2x = 6x + 6 + 6

                                 <u>x² - 4x - 12 = 0</u>

                                (x - 6) (x + 2) = 0

                             x = 6    and    x = -2

The numbers are  ('6' and '8'), or ('-2' and 0).

I honestly don't know what to make of the second pair.
But the first pair satisfies the description:

              The product (48) = 3 x the sum (3 x 14 = 42) plus 6.

So '6' and '8' completely work, except that they're not <u>odd</u> integers.

Find the midpoint of the segment between the points (17,−11) and (−14,−16)
Viefleur [7K]

Answer:

(1.5, -13.5)

Step-by-step explanation:

Midpoint Formula: (\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )

Simply plug in our coordinates into the formula:

x = (17 - 14)/2

x = 3/2

y = (-11 - 16)/2

y = -27/2

MaRussiya [10]
<h3>Answer:  D) 1/24</h3>

=============================================================

Explanation:

There are 4 digits to pick from and 4 slots to fill, so there are 4! = 4*3*2*1 = 24 different codes possible.

If we want the code to start with 371, then that must mean 5 is the only thing left for that fourth slot. In short, there's only one code that starts with 371 and that code is 3715

We have one code we want (3715) out of 24 total, which is why the answer is 1/24 (choice D)
