Answer:

\sqrt{16 \times9 \times 3  \:   \: equals \:4 \times 3 \times  \sqrt{3that \: eauas \: 12 \sqrt{3} } }

Step-by-step explanation:

Square root of 16 ×9×3= square root of 432

square root of 16 =4

square root of 9 =3

That will equal 4×3× square root of 3 which finally equals to 12 square root of 3.

Answer: 12\sqrt{3}

On a keyboard, you would write 12*sqrt(3)

==============================================

Explanation:

Find the prime factorization of 432 to get

432 = 2^4*3^3

That allows us to do the following steps

\sqrt{432} = \sqrt{2^4*3^3}\\\\\sqrt{432} = \sqrt{2^2*2^2*3^2*3^1}\\\\\sqrt{432} = \sqrt{2^2}*\sqrt{2^2}*\sqrt{3^2}*\sqrt{3^1}\\\\\sqrt{432} = 2*2*3*\sqrt{3}\\\\\sqrt{432} = 12\sqrt{3}\\\\

------------------

Or you could do something like this

\sqrt{432} = \sqrt{144*3}\\\\\sqrt{432} = \sqrt{144}*\sqrt{3}\\\\\sqrt{432} = 12\sqrt{3}\\\\

Plz help me with this i do not understand math stuff
Zarrin [17]

Answer: Pink choice: y= -6x -2

Step-by-step explanation:

In order to be parallel, the slope must be the same. You find the slope as the number or fraction connected to x. <em>("co-efficient" of x in math talk)</em>

In the given equation, that is -6.  (So that knocks out the first two choices)

The other thing to look at is the y-value of the given coordinate,(-1,4)

<em>(The y-value is the second number in the coordinate (x.y) is the pattern)</em>

and compare it to the the last number in the equations in the choices and     Here the Yellow choice has y= -6x + 4 so this line can't pass through the coordinate given, because  +4 in this equation is where the line crosses the y-axis. ("y-intercept"  in math talk)  So yellow choice is out!

The attachment shows what the graphs of the choices look like.

The black line is the correct answer. The given coordinate (-1,4) is the labeled red spot. The blue line is the given equation. (You can see where it "intercepts the y-axis on the +3)   And the green line also has the -6 slope, but misses the point and intercepts the y-axis at 4.)    

I hope the diagram and explanation helps you understand better. It can be confusing.

A trapezoid has a height of 6 feet. The measures of the bases are 12 units and 18
Alik [6]

The area of this trapezoid is 90 square feet.

<h3>Explanation : </h3>

Before we know the answer, let's we know the formula first. The formula for count the area of trapezoid is :

\boxed {\bold {A = \frac {(a+b) \times h}{2}}}

If :

  • A = area of trapezoid
  • a = bottom bases of trapezoid
  • b = top bases of trapezoid
  • h = height of trapezoid

Okay, let's we count its :

We know that :

  • a = bottom bases of trapezoid = 18 feet
  • b = top bases of trapezoid = 12 feet
  • h = height of trapezoid = 6 feet

Question : A = area = ... ?

Answer :

A = \frac {(a+b) \times h}{2} \\ A = \frac {(12+18) \times \cancel6}{\cancel2} \\ A = 30 \times 3 = 90  \: {ft}^{2}

Does there exist 2 distinct prime numbers such that their product is a square number?​
satela [25.4K]

Answer:

NO.

Step-by-step explanation:

If the 2 prime numbers are odd then the product cannot be a square number because the only factors are the original prime numbers.  If one of the prime numbers is 2 then the product will be an even number , but again the only factors will be 2 and the other prime number.

So the answer is No.
