I am giving a lot of points lease give explanation Which is the equation of a hyperbola with directrices at x = ±2 and foci at (6, 0) and (−6, 0)?
x squared over 12 minus y squared over 24 equals 1
x squared over 12 minus y squared over 48 equals 1
y squared over 12 minus x squared over 24 equals 1
y squared over 48 minus x squared over 12 equals 1

Calculate the speed of a wave that has a wavelength of 8 meters and a frequency of 16 meters per second (m/s).

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

i believe the correct answer is b.
