(2x3 – 3x2 + 6x + 4) = (2x + 1)

x= -1

Step-by-step explanation:

(2x3-3x2+6x+4)=(2x+1)

6x+4=2x+1

6x=2x-3

3x=-3

x=-1

Option (B)

Step-by-step explanation:

In this question we have to select the wave diagram that represents  a dim red sunset on the right side to the light from an intense ultraviolet bug light on the left side.

The wavelength of red light is from 635 nm to 700 nm. While the wavelength of ultraviolet light lies from 10 nm to 400 nm. It is clear that the wavelength of the red light is more as compared to ultraviolet light.

We know that the distance between two consecutive crests and trough is called wavelength. Also, the amplitude of dim light is small and the wavelength of violet light is large.

So, the option (b) shows the dim red sunset on the right side to the light from an intense ultraviolet bug light on the left side.
