The polynomial below is a perfect square trinomial of the form A2 - 2AB + B2.
seropon [69]

Answer: Option B.

Step-by-step explanation:

Given the polynomial:

16x^2-36x+9

 Observe that 16x^2 and 9 are perfect squares. Then, you can rewrite the polynomial in this form:

(4x)^2-36x+(3)^2

You can identify that:

A=4\\B=3

Then, we can check if 2AB=36

 2(4x)(3)=36x\\\\24x\neq 36x\\\\2AB\neq36x

Since 2AB\neq36x, the polynomial 16x^2-36x+9 <em>IS NOT </em>a perfect square trinomial of the form A^2 - 2AB + B^2

Can you help me with this?<br> (I will give one of you brainliest)
Degger [83]

Answer:

1) \sqrt{9} and \sqrt{16} (between 3 and 4)

Explanation: \sqrt{9} and \sqrt{16} are the closest WHOLE squares root to \sqrt{12}; any other square roots wouldn't give us a whole number, or they're farther away from

2) -\sqrt{144} and -\sqrt{169} (between -(12) and -(13))

What is 24% of 1350 I will give 75 points
nika2105 [10]
<h3>Answer:</h3><h2>324.</h2><h3>Step-by-step explanation:</h3>

To find 24% of 1,350, you must multiply 24% by 1,350.

To do this problem, we must turn the numbers to fractions.

Twenty-Four hundredths, 24 / 100 is your fraction for 24%.

Put 1,350 over 1 since 1,350 is a whole number.

So:

24 / 100 x 1,350 / 1.

1350 x 24 = 32400, 100 x 1 = 100.

Your answer is 32,400 / 100.

Get rid of the 2 zeroes in 400 and 100.

It should be 324 / 1.

Since 1 is just the number 1, the answer is 324.

If you have any questions, feel free to comment below.

Merry Christmas!

The perimeter of a square is 66.8 cm. What is the side lengh of the square​
mylen [45]

Side length = 16.7 cm

Solution:

Perimeter of a square given = 66.8 cm

In a square four sides are equal.

The perimeter of a square = 4 × side

⇒ 4 × side = 66.8 cm

Divide both sides of the equation by 4 to equal the expression.

⇒ side = 66.8 ÷ 4

⇒ side = \frac{66.8}{4}

⇒ side = 16.7 cm

Hence, the side length of the square is 16.7 cm.

**22 POINTS** Please solve this fraction as a difference
Ghella [55]

Answer:

\dfrac{x}{4}-\dfrac{7}{12}

Step-by-step explanation:

The fraction is the equivalent of ...

\dfrac{1}{12}{(3x-7)

and the distributive property applies.

=\dfrac{1}{12}(3x)-\dfrac{1}{12}(7)\\\\=\dfrac{3\cdot x}{3\cdot 4}-\dfrac{7}{12}\\\\=\dfrac{x}{4}-\dfrac{7}{12}
