Solve for k.

k + 4 over 2 = 3

K = 1

Step-by-step explanation:

K + 2 = 3

K = 3 -2

K = 1

K=2

Step-by-step explanation:

K+4 / 2 = 3

If you input 2 into the equation you get 3.

2+4=6

6/2 = 3

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
