If two sides of a triangle are 9 and 20, what range of numbers would be possible for the length of the third side?

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 question 1 is -8, 28.

step-by-step explanation:

cause it equals more
