solve. be sure to show your work as taught in the lesson:

7x - 3 > 46.

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it

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:

54/3 is 18 so 18 is your answer
