Answer:
x=3
Step-by-step explanation:
substitute into the equation
Step-by-step explanation:
diagonals bisect
5u-10= 2u+2
3u = 12
u=4
v/3 = 6
v=18
The relationship between wavelength and frequency is expressed by the equation λν=c where λ is the wavelength, v is the frequency and c is the speed of light which has a value of 3x10^8 m/s.
λν=c
λ(3 × 10^9)= 3x10^8
λ = 0.1 m
Hope this answers the question.
