The product of 3 consecutive odd numbers is 3,315. Enter a simplified expression for finding the numbers. Let n be the first odd

grin007 [14]

Answer:

$n^3+6n^2+8n=3315$

Step-by-step explanation:

Let n be the first odd number.

The 2nd consecutive odd number would be $n+2$ and 3rd consecutive odd number would be $n+2+2=n+4$ .

We have been given that the product of 3 consecutive odd numbers is 3,315. The product of 3 consecutive odd numbers would be $n(n+2)(n+4)$ .

Now we will equate the product with 3315 as:

$n(n+2)(n+4)=3315$

Let us simplify the left side of equation.

$(n\cdot n+n\cdot 2)(n+4)=3315$

$(n^2+2n)(n+4)=3315$

Now, we will apply FOIL to find the product of left side as:

$n^2\cdot n+n^2\cdot 4+2n\cdot n+2n\cdot4=3315$

$n^3+4n^2+2n^2+8n=3315$

$n^3+6n^2+8n=3315$

Therefore, our required equation would be $n^3+6n^2+8n=3315$ .

The length of the sides of a square measure 2x-5. The length of a rectangle measures 2x, and the width measures x + 2. For what

vladimir1956 [14]

Answer:

$x = 12$

Step-by-step explanation:

Perimeter of a square:

The perimeter of a square of side x is given by:

$P_s = 4x$

Perimeter of a rectangle:

The perimeter of a rectangle of length l and width w is given by:

$P_r = 2(l + w)$

The length of the sides of a square measure 2x-5.

This means that the perimeter of the square is:

$P_s = 4(2x - 5) = 8x - 20$

The length of a rectangle measures 2x, and the width measures x + 2.

This means that the perimeter of the rectangle is:

$P_r = 2(2x + x + 2) = 2(3x + 2) = 6x + 4$

For what value of x is the perimeter of the square the same as the perimeter of the rectangle?

This is x for which:

$P_s = P_r$

$8x - 20 = 6x + 4$

$8x - 6x = 20 + 4$

$2x = 24$

$x = \frac{24}{2}$

$x = 12$
