Answer:

8m^5

Step-by-step explanation:

Well we can simplify the numerator, by multiplying the 4 by the 6 and the m^3 and m^4 (add the exponents, explained in one of my previous answers I think)

This gives us the fraction: \frac{24m^7}{3m^2}

We can now divide the m^7 by m^2 by subtracting the exponents, and the reason why this works, is you're simply cancelling out the m's, If we express this in expanded form we have the following fraction: \frac{24 * m * m * m * m * m * m * m}{3 * m * m}

Since there is two m's in the denominator and there is also two (more than two) m's in the numerator, we can cancel those two m's out, and we get the fraction:

\frac{24 * m * m * m * m * m}{3} which can be simplified in exponent form as: \frac{24m^5}{3}, now all we have to do is divide the 24 by the 3, to get 8

This gives us the answer: 8m^5

Describe how you would use the distributive property to simplify (39x5)
mrs_skeptik [129]

Hi there!

Answer:

<u><em>=195x and x=195</em></u>

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

Multiply by the numbers.

39*5=195

195/5=39

195/39=5

5*39=195

=195x and x=195

Hope this helps!

Solve using algebraic equation: <br> 5sin2x=3cosx<br><br> (No exponents)
DaniilM [7]
5\sin2x=3\cos x\iff10\sin x\cos x=3\cos x

by the double angle identity for sine. Move everything to one side and factor out the cosine term.

10\sin x\cos x=3\cos x\iff10\sin x\cos x-3\cos x=\cos x(10\sin x-3)=0

Now the zero product property tells us that there are two cases where this is true,

\begin{cases}\cos x=0\\10\sin x-3=0\end{cases}

In the first equation, cosine becomes zero whenever its argument is an odd integer multiple of \dfrac\pi2, so x=\dfrac{(2n+1)\pi}2 where n[/tex ]is any integer.\\Meanwhile,\\[tex]10\sin x-3=0\implies\sin x=\dfrac3{10}

which occurs twice in the interval [0,2\pi) for x=\arcsin\dfrac3{10} and x=\pi-\arcsin\dfrac3{10}. More generally, if you think of x as a point on the unit circle, this occurs whenever x also completes a full revolution about the origin. This means for any integer n, the general solution in this case would be x=\arcsin\dfrac3{10}+2n\pi and x=\pi-\arcsin\dfrac3{10}+2n\pi.

How do you factor quadratics by grouping
Kaylis [27]
Here's an example Its also call the 'ac' method:-

factor  2x^2 - 13x - 15

Multiply first coefficient by last number  which is 2*-15 = -30

Now we need 2 factors of -30 which will when added give - 13:-

-15 and 2  looks good. So we  can write:-

2x^2 - 13 x - 15

= 2x^2 + 2x - 15x - 15 

factor by grouping first 2 and last 2 terms , we get:-

= 2x(x + 1) - 15(x + 1)   

the x+1 is common so we have:-

(2x - 15)(x + 1)   Answer

Hope this helps.
