Only 100 points for you to answer to my math word problem question but please don’t post a very useless answer on The Brainly! &

gt;:(
Consider the following expression that looks like this:\frac{3x^{3}y*6xy^{3}}{(-3xy)^{2}}.

What can you describe the advantages and the disadvantages of each method?

Please help me as soon as possible will get the brainliest award if your answers are the best step-by-step explanations and an efforts into it, well anyways, good luck on answering the math word problem question of my last year’s math word problem homework from The Hung Vuong Learning Centre Incorporated, and I will be there checking the answers to see if it’s appropriate. :)

We need to simplify it

\\ \tt\longmapsto \dfrac{3x^36xy^3}{(-3xy)^2}

Apply

  • (ab)^n=a^nb^n
  • a^n+a^m=a^m+n

\\ \tt\longmapsto \dfrac{18x{3+1}y^{1+3}}{9x^2y^2}

\\ \tt\longmapsto \dfrac{18x^4y^4}{9x^2y^2}

  • a^m/a^n=a^m-n

\\ \tt\longmapsto 2x^2y^2

hope it helps

Answer:

\dfrac{3x^3y*6xy^3}{(-3xy)^2}=2x^2y^2

Step-by-step explanation:

\dfrac{3x^3y*6xy^3}{(-3xy)^2}

<u />

<u>Numerator</u>

Multiply the constants, and apply the exponent rule: a^b\cdot \:a^c=a^{b+c}

3x^3y*6xy^3=(3*6)x^{(3+1)}y^{(1+3)}=18x^4y^4

<u>Denominator</u>

Apply the exponent rule:  \left(-a\right)^n=a^n,\:\quad \mathrm{if\:}n\mathrm{\:is\:even}

(-3xy)^2=(3xy)^2

Apply the exponent rule:  \quad \left(a\cdot \:b\right)^n=a^nb^n

(3xy)^2=3^2x^2y^2=9x^2y^2

Therefore,

\dfrac{3x^3y*6xy^3}{(-3xy)^2}=\dfrac{18x^4y^4}{9x^2y^2}

Factor 18 and cancel the common factor 9:

\implies \dfrac{18x^4y^4}{9x^2y^2}=\dfrac{9*2x^4y^4}{9x^2y^2}\\\\\\\implies \dfrac{9*2x^4y^4}{9x^2y^2}=\dfrac{2x^4y^4}{x^2y^2}

Apply the exponent rule: \dfrac{x^a}{x^b}=x^{a-b}

\implies \dfrac{2x^4y^4}{x^2y^2}=2x^2y^2

19. In the triangle ABC, the side lengths are BC = 14 and AC = 7. What's the angle measurement of B?
mr Goodwill [35]

Answer:

Is not possible to compute the angle under those conditions.

Step-by-step explanation:

You need more information, I will be more specific, there is a book called "Geometry" by Moise Downs where the following theorem is stated on the chapter 7.

Let    ΔABC   and   ΔDEF   be two triangles  where AB = DE  and AC = DF  if  

∠A   >  ∠D     then   BC > EF,   which in simple terms means that, if two sides are equal, the angle between them can vary as much as you want and that will directly imply the size of the third size of your triangle.  

Therefore, there is information missing in order to solve the question

The graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic.
diamong [38]

Answer:

<em>B)</em><em> 8.9 lbs </em>

<em>C)</em><em> 9.5 lbs </em>

<em>D)</em><em> 9.8 lbs </em>

<em>E)</em><em> 10.4 lbs</em>

Step-by-step explanation:

From the graph, 9.5 is the mean of the sample and 0.5 is the standard deviation of the sample.

As we have to find the weights that lie within the 2 standard deviations of the mean i.e

=9.5\pm 2(0.5)

=8.5,10.5

Among the given weights only 8.9 lbs, 9.5 lbs, 9.8 lbs, 10.4 lbs will lie within 2 standard deviations of the mean.
