k2-6k4-(3k4+k2+2)
Distribua o sinal negativo:
=k2-6k4+-1(3k4+k2+2)
=k2+-6k4+-1(3k4)+-1k2+(-1)(2)
=k2+-6k4+-3k4+-k2+-2
Combine os termos semelhantes:
=k2+-6k4+-3k4+-k2+-2
=(-6k4+-3k4)+(k2+-k2)+(-2)
=-9k4+-2
Responda:
=-9k4-2

Answer: 
Step-by-step explanation:
If we assume that the boys and girls are equally likely, so the probability of having a girl is equal to probability of having a boy = .
Let B = Event of having a boy.
G= Event of having a girl.
Since both events are independent of each other . (Events that do not depends on each other.)
So irrespective of the four baby boy , the probability that the fifth child is a boy =
Therefore , the probability of a couple having a baby boy when their fifth child is born, given that the first four children were all boys=
Responder:
x = 42,4
Explicación paso a paso:
Podemos encontrar el valor de x ya que no se nos dice qué buscar
La suma de dos ángulos suplementarios es 180 grados, por lo tanto;
2x - 14 + 3x - 18 = 180
2x + 3x - 32 = 180
5 veces = 180 + 32
5 veces = 212
x = 212/5
x = 42,4
Por tanto, el valor de x es 42,4
