Simplify this algebraic expression completely. 10y- 3(y+ 5) o a. 7y+2 o b. 7y-15 o c. 7y-5 o d. 7y+5

is there any photos or whatever?

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:
