D) 12x^3 - 4x^2<br> Factorise fully
Vinvika [58]

Answer:

The answer for the equation is 4x^2 (3x - 1).

Step-by-step explanation:

Solve:

12^3 - 4x^2

-Factor out the 4 :

12^3 - 4x^2

4(3x^3 - x^2)

-Factor out the x^2 :

4(3x^3 - x^2)

x^2 (3x - 1)

-Then, you rewrite the complete factored expression:

x^2 (3x - 1)

4x^2 (3x - 1)

So, the answer is 4x^2(3x - 1).

Sali throws an ordinary fair 6-sided dice once.
UNO [17]

Answer:

a=p=\frac{1}{6}\\\\b. \ p=\frac{1}{12}\\\\c.\ 1H,1T,2H,2T,3H,3T,4H,4T,5H,5T,6H,6T

Step-by-step explanation:

a. A fair dice has 6 sides with unique identities.

-The sample space of one throw is 6 and each face has an equal chance of showing up.

-The probability of a 6 is calculated as:

p(six)=\frac{1}{6}\\\\or \ =0.1667

Hence, the probability of a 6 is \frac{1}{6}

b.A fair die has  6 unique faces.

-Two throws will have a sample space of 12.

-Each face has an equal probability of appearing twice.

-The probability of a 6 on both throws is:

P(six)=2\times \frac{1}{6}\\\\=\frac{1}{12}

c. A coin has 2 sides(head, tail) and a die has 6 sides.

-The total sample space for the simultaneous throw of a coin and die is 12.

-The resultant sample space is :

1H,1T,2H,2T,3H,3T,4H,4T,5H,5T,6H,6T

12480 es divisible de 6<br><br> Doy 50
kupik [55]

12,480 es par y la suma de sus digitos da un multiplo de 3, por ello concluimos que es divisible por 6.

<h3></h3><h3>¿Como saber si un número es divisible por 6?</h3>

Para que un número sea divisible por 6 debe cumplir dos condiciones.

  • Ser par.
  • La suma de sus digitos debe ser multiplo de 3.

En este caso tenemos 12,480, que sabemos que es par.

La suma de sus digitos da:

1 + 2 + 4 + 8 + 0 = 15

15 es multiplo de 3.

Entonces este número cumple ambas condiciones, por lo que concluimos que 12,480 es divisible por 6.
