Find the non-extraneous solutions of sqrt(x + 3) - 4 = x - 1 . (1 point) 1- x = - 3 and x = - 2
2- x = - 2
3- x = - 3
4- x = 5

x+3=(x+3)^2

x+3=(x+3)(x+3)

x+3= x^2+6x+9

x=x^2+6x+6

0=x^2+5x+6

0=(x+3)(x+2)

x=-2

x=-3

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
