The dimensions of a box of paper clips are 3.1 inches by 1.6 inches by 1 inch. If there are 100 paper clips guaranteed to be in

Cloud [144]

Answer: 0.0496 in^3

First, find the volume of the box, in inches:

3.1 * 1.6 * = 4.96

Then, find the density of the 100 paper clips:

(let d = density)

100d = 4.96

d = 0.0496

What pattern is represented by the polynomial ? 4x^2+12x+9 A. difference of two squares B. general trinomial C. perfect square t

bixtya [17]

Answer:

Option C - Perfect square trinomial.

Step-by-step explanation:

Given : Polynomial $4x^2+12x+9$

To find : What pattern is represented by the polynomial?

Solution :

First we make the polynomial in factor form,

Polynomial $4x^2+12x+9$

Since, it is not factor clearly so try to make the square.

Taking 4 common,

$=4(x^2+3x+\frac{9}{4})$

Identifying the x and y terms in the identity, $(x+y)^2=x^2+y^2+2xy$

$=4((x)^2+2\times x\times \frac{3}{2}+(\frac{3}{2})^2)$

Factor the perfect square trinomial,

$=4(x+\frac{3}{2})^2)$

Therefore, The pattern polynomial represent is perfect square trinomial.

So, Option C is correct.
