Is this correct 1 problem 15 points

First, we should simplify this to see if it is true. The left side is already in simplest form, but the right side isn't. It can be distributed, which is multiplying the numbers inside the parenthesis by two like this: . This equation has many solutions, because both sides both go through the same changes. So you are correct. Nice job. :)

step-by-step explanation:

not really sure

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:
