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.

Quadrilateral RPQS is a rectangle. Label the missing measures.
Taya2010 [7]

Answer:

Part 1) PR=9\ units

Part 2) PQ=12\ units

Part 3) PS=15\ units

part 4) QR=15\ units

Part 5) RT=7.5\ units

Step-by-step explanation:

we know that

In a rectangle opposite sides are parallel and congruent

The measure of each interior angle is 90 degrees

The diagonals are congruent and bisect each other

step 1

Find the length of side PR

we know that

PR=QS ----> by opposite sides

we have

QS=9\ units

therefore

PR=9\ units

step 2

Find the length of side PQ

we know that

PQ=RS ----> by opposite sides

we have

RS=12\ units

therefore

PQ=12\ units

step 3

Find the length of diagonal PS

we know that

PS=2PT---> the diagonals bisect each other

we have

PT=7.5\ units ---> given problem

therefore

PS=2(7.5)=15\ units

step 4

Find the length of diagonal QR

we know that

QR=PS---> the diagonals are congruent

we have

PS=15\ units

therefore

QR=15\ units

step 5

Find the length of RT

we know that

QR=2RT---> the diagonals bisect each other

we have

QR=15\ units

substitute

15=2RT\\RT=7.5\ units

A line has an c intercept of 3 and a y intercept of negative 6. What is the slope intercept form of it’s equation
Schach [20]

Answer:

y = 2x - 6

Step-by-step explanation:

Slope-intercept form is  y = mx + b, where m is the slope and b is the y-intercept.

The y-intercept is already given and is -6.

By c intercept, I am assuming you meant x-intercept.  With an x-intercept of 3, the point is (3,0).  With a y-intercept of -6, the point is (0,-6).

Use the two points to find the slope using the following equation.

m=\frac{y_{2}-y_{1}  }{x_{2}- x_{1} }

Plug the points into their respective positions and solve.

m=\frac{-6-0}{0-3}\\ m=\frac{-6}{-3} \\m=2

The slope is 2.

Your equation is  y = 2x - 6.

A square patio has an area of 170 square feet. How long is each side of the patio to the nearest tenth?
Pavlova-9 [17]
Since we know that squares have the same length on all sides, you would find the square root of 170
√170=13.03840481
rounded to the nearest tenth would be 13.1

You can check your work by multiplying 13.1 by 13.1 which equals 170.3

I try to explain the problem and give the answer, I hope this helps!
