Answer:

x^3+3x^2+5x+4

Step-by-step explanation:

We are given that  product of binomial and trinomial is

x^3+3x^2-x+2\times 2+6x-2

We have to find an expression equivalent to given product after it has been simplified.

x^3+3x^2-x+2\times 2+6x-2

Rearrange the terms in the given expression

x^3+3x^2-x+6x+2\times 2

Combine like terms

x^3+3x^2+5x+2\times 2

x^3+3x^2+5x+4

Answer:

x^3+3x^2+5x+2

Step-by-step explanation:

The product of a binomial and a trinomial is

x^3+3x^2-x+2 \times 2 +6x-2

we have to simplify that

x^3+3x^2-x+4+6x-2

bringing the like terms together we get

x^3+3x^2-x+6x+4-2

-x+6x = 5x

-2+4 = 2

hence our expression becomes

x^3+3x^2-x+6x+4-2=x^3+3x^2+5x+2

Which inequality is equivalent to x-6/x+5≥x+7/x+3?
yawa3891 [41]
To find equivalent inequalities you have to work the inequality given.

The first step is transpose on of sides to have an expression in one side and zero in the other side:

  x - 6        x + 7
--------- ≥  --------
  x + 5       x + 3

=>

  x - 6          x + 7
--------- -  --------   ≥ 0
  x + 5       x + 3

=>

 (x - 6) (x + 3) - (x + 7) (x + 5)
--------------------------------------- ≥ 0
          (x + 5) (x + 3)

=>

 x^2 - 3x - 18 - x^2 - 12x - 35
--------------------------------------- ≥ 0
         (x + 5) (x + 3)

           15x + 53
-     -------------------   ≥ 0
       (x + 5) (x + 3)

That is an equivalent inequality. Sure you can arrange it to find many other equivalent inequalities. That is why you should include the list of choices. Anyway from this point it should be pretty straigth to arrange the terms until making the equivalent as per the options.

An investment firm wants to create a billboard that displays an enlarged $1,000,000 bill. The actual size of the bill is 2.61 in
Mandarinka [93]

We know how wide the billboard will be. Therefore, to know how much the original image should be enlarged, you must divide the final width of the billboard between the current width of the invoice.

We know both data, then we perform the operation:

48 feet /6.14 inches = 7.81 feet / inches .


Therefore the correct answer is option D. 1″ = 7.81′

For the bill to cover the billboard, the bill must be expanded by a factor of 7.81 feet long per inch long that has the original image.
