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.

The slope of the line passes through the points (3,-6) and (7,y) is -2/3. Find y.
kirza4 [7]
-6-y / 3-7 = -2/3

-6-y / -4 = -2/3

Multiply through by  -12:-
3(-6-y) = 8

-18 - 3y = 8
3y =  - 26

y = -8 2/3
