Please solve: x^2+4x-8=0

Bezzdna [24]

$x^2+4x-8=0\\\\\underbrace{x^2+2x\times2+2^2}_{use:(a+b)^2=a^2+2ab+b^2}-2^2-8=0\\\\(x+2)^2-4-8=0\\\\(x+2)^2-12=0\\\\(x+2)^2=12\iff x+2=\sqrt{12}\ or\ x+2=-\sqrt{12}\\\\x=\sqrt{4\times3}-2\ or\ x=-\sqrt{4\times3}-2\\\\x=\sqrt4\times\sqrt3-2\ or\ x=-\sqrt4\times\sqrt3-2\\\\\center\boxed{x=2\sqrt3-2\ or\ x=-2\sqrt3-2}$

Helga [31]

Answer:

r = 4

Step-by-step explanation:

First we have to subtract 21.50 from 20.50 because that is how much money it takes to get inside the amusement park.

21.50 - 20.50 = 1

Right now you have only 1 dollar left. now we have to divide 100 by 25 to see how many times you can ride.

100/ 25 = 4

You can ride 4 times
