The pair of shoes you want is on sale for 25% off. If the shoes originally cost $65, how much is the sale price

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:

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu
