Answer:

Option B (n³ + 4n² + 8n - 16)

Step-by-step explanation:

In this question we have to add two expressions given

( 2n³ + 4n² - 7 ) and ( -n³ + 8n - 9 )

( 2n³ + 4n² - 7 ) + ( -n³ + 8n - 9 )

Now we group the similar terms

( 2n³ - n³ ) + 4n² - ( 7 + 9 ) 8n

= n³ + 4n² - 16 + 8n

= n³ + 4n² + 8n - 16

Option B (n³ + 4n² + 8n - 16) is the correct answer.

If the area of a rectangle in terms of x is x2 + 15x + 26 / 6x2 and its width is x2 - 3x - 10 / 30x3 Find the length of the rect
Veseljchak [2.6K]

Answer:

The length of the rectangle is;

5x(x+13)/(x-5)

Step-by-step explanation:

Mathematically, we know that the area of a rectangle is the product of the length and width of the triangle

To find the length of the rectangle, we will have to divide the area by the width

we have this as;

(x^2 + 15x + 26)/6x^2 divided by (x^2-3x-10)/30x^3

thus, we have ;

(x^2 + 15x + 26)/6x^2 * 30x^3/(x^2-3x-10)

= (x^2+15x+ 26)/(x^2-3x-10) * 5x

But;

(x^2 + 15x + 26) = (x+ 2)(x+ 13)

(x^2-3x-10) = (x+2)(x-5)

Substituting the linear products in place of the trinomials, we have;

(x+2)(x+13)/(x+2)(x-5) * 5x

= 5x(x+13)/(x-5)
