Answer:
D - x = 19 x = -17
Step-by-step explanation:
Factor the equation to make the problem easier - you should have this:
(x - 18) (x + 18) = 1
Set each binomial to 1:
x - 18 = 1
x + 18 = 1
This should give you x = 19 and x = -17
Step-by-step explanation:
We have,
The wavelength of yellow light, 
Frequency of yellow light, 
It is assumed to find the speed of light in the yellow light.
The speed of a wave is given in terms of wavelength and frequency as :

So, the speed of light in a shade of yellow light is
.
