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.

Identify the angles that each have a measure of 124º.
Natali5045456 [20]

Answer:

Angle 1, angle 3 and angle 7 will be the equal angles.

Step-by-step explanation:

In the figure attached,

Two lines are parallel and a transversal line is intersecting these parallel lines.

Congruent angles to the angle measuring 124° will be,

m(∠7) = 124° [Vertical angles]

m(∠1) = 124° [Corresponding angles]

m(∠3) = 124° [Alternate interior angles]

Therefore, ∠1, ∠7 and ∠3 will measure the same as 124°.

FiftyFifty adult men in the United States are randomly selected and measured for their body mass index​ (BMI). Based on that​ sa
Fynjy0 [20]

Answer: (23.3,\ 29.7)

Step-by-step explanation:

The confidence interval for population mean is given by :-

\overline{x}\pm ME., where \overline{x} is the sample mean and ME is the margin of error .

Given : The sample mean : \overline{x}=26.5

Margin of error : ME=3.2

Then , the range of values​ (confidence interval) likely to contain the true value of the population parameter will be :-

26.5\pm 3.2=(26.5-3.2,\ 26.5+3.2)=(23.3,\ 29.7)

Hence, the range of values​ likely to contain the true value of the population parameter =  (23.3,\ 29.7)

I have a question for you guys.
NeX [460]

If George's driveway is a rectangle 12.2 m by 3.0 m, its dimensions in cm are

... 1220 cm long × 300 cm wide × 2 cm deep

Thus the volume of gravel required is

... (1220 × 300 × 2) cm³ = 732,000 cm³

George needs about 0.732 bags, so he will probably need to buy 1 bag.

Find the solution for the following: Three backpackers cooked rice for dinner. The first one gave 400g of rice and the second 20
victus00 [196]

Answer:

First backpacker should receive $4 and the second one $2

Step-by-step explanation:

notice that the total amount of rice for the three is 600 g.

Then, the first one that gave 400 g contributed 400 out of 600, that is 400/600 = 2/3

The second one contributed 200 out of 600, that is 200/600 = 1/3

then the first one should receive 2/3 of the $6 = (2/3) x 6 = $4

and the second one should receive 1/3 of the %6 = (1/3) x 6 = $2
