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.

Plug the point (-1,20) into the equation.

20 = a|-1|+7

13 = a|-1|

13 = a ⋅ 1

a= 13

Zabato is thinking of a number. Three times the sum of the number and ten is the same as eight time the number. What is zabato's

9966 [12]

Answer:

Zabato is thinking of 6

Step-by-step explanation:

I first set it up as an equation based on the word problem you have given me

(n + 10)3 = 8n

Distribute the 3

3n + 30 = 8n

Isolate n

3n - 8n +30 - 30 = 8n - 8n - 30

-5n = -30

-5n/-5 = -30/-5

n = 6

To check replace 6 with n

(6 + 10)3 = 8 (6)

(16)3 = 48

48 = 48

Which coordinate pairs make the equation x-9y=12 true?

asambeis [7]

Answer:

(12,0) and (3, -1) and (0,-4/3)

Step-by-step explanation:

To find if a point makes an equation true, just substitute its x and y values in in the equation and simplify.

1) Let's test the point (12,0). Substitute 12 for x and 0 for y in the equation:

$x-9y=12\\(12)-9(0)=12\\12-0=12\\12=12$

12 does equal 12, so (12,0) makes the equation true.

2) Let's test the point (0, 12). Substitute 0 for x and 12 for y in the equation:

$x-9y=12\\(0)-9(12) = 12\\0-108 = 12\\-108 = 12$

However, -108 does not equal 12, so (0,12) does not make the equation true.

3) Let's test the point (3, -1). Substitute 3 for x and -1 for y in the equation:

$x-9y=12\\(3)-9(-1) = 12\\3 + 9 = 12\\12 = 12$

12 does equal 12, so (3, -1) makes the equation true.

4) Let's test the point (0, -4/3). Substitute 0 for x and -4/3 for y in the equation:

$(0) -9(-\frac{4}{3} ) = 12\\0 + \frac{36}{3} = 12\\0 + 12 = 12 \\12 = 12$

12 does equal 12, so (0, -4/3) makes the equation true.
