Answer:
X = - 2 or X = 2
Step-by-step explanation:
*completing the square*
X^2 - 4 = 0
X^2 = 4
X = +-√4
x = +-2
x= -2, 2
*factoring*
X^2 - 4 = 0
(x-2)(x+2) = 0
|. |
x = 2, x = -2
________________________________
(x-2)(x+2) = x(x+2) - 2(x+2) = x^2 + 2x - 2x - 4 = x^2-4
Answer:
Los partidos ganados representan 25 de 40, es decir, 25/40= 0,625=62,5%
Los partidos empatados representan 10 de 40, es decir, 10/40=0,25=25%
Los partidos perdidos representan 5 de 40, es decir 5/40=0,125=12,5%
Si los sumamos : 100%

hola aqui te dejo las respuestas Pero quieres ser mi amiga
Without any numbers this is hard to calulate
Remember you can do anything as long as you do it to both sides
add 7 to both sides
x>5
the solution set could look like
x>5
or
S={x|x>5} or
(5,∞)
