Answer:

Step-by-step explanation:
The speed of light is
and its frequency is
.
The speed of light is given as:
c = λ * f
where λ = wavelength of light
f = frequency of light
Therefore, the wavelength is given as:
λ = c / f
=> λ = 
=> λ = 
The wavelength of the light is 
Answer:
x = -4/5 = -0.800
Step-by-step explanation:
Pull out like factors :
-12 - 15x = -3 • (5x + 4)
Solve :
-3 = 0
Solve :
5x+4 = 0
5x = -4
<u><em>x = -4/5 = -0.800</em></u>
