Answer:

3m(1-2m)(4m²+2m+1)

Step-by-step explanation:

3m - 24m⁴   (factorize 3m)

=3m(1) - 3m(8m³)

= 3m (1-8m³)

=3m (1³ - 2³·m³)

=3m [ 1³ - (2m)³ ]

recall the cubic formula:

a³ + b³ = (a+b)(a² - ab + b²)

if we apply this to [ 1³ - (2m)³ ], we will eventually get

= 3m(1-2m)(4m²+2m+1)

edit: last step got cut off. fixed

edit 2: by request, i added more detail to the last 2 steps

NEED RN, WORTH 20! <br> What is the value of x?
max2010maxim [7]

Answer:

x = 5.625

Step-by-step explanation:

<u>Step 1:  Make an expression</u>

<u />\frac{3}{4} = \frac{x}{7.5}

<u>Step 2:  Cross Multiply</u>

<u />\frac{3}{4} = \frac{x}{7.5}

4 * x = 7.5 * 3

4x = 22.5

<u>Step 3:  Divide both sides by 4</u>

<u />4x / 4 = 22.5 / 4

x = 5.625

Answer:  x = 5.625

\mathbb{A~N~S~W~E~R~:}

= r · 2

➡ \Huge \sf \mathbb \color{}\underline{\colorbox{ANSWER~WITH~EXPLANATION ~!}{}}

\mathfrak{apply~the~fraction~rule:  }   a \frac{b}{c} =\frac{a~. ~b }{c}

\mathfrak{apply~rule:  }  a · 1 = a

r · 1 · 4 = r · 4

=\frac{r~.~4}{2}

\mathfrak{divide~the~numbers~:  } \frac{4}{2} = 2

= r · 2

So, your answer will be is :

= r · 2
