Which value must be added to the expression x2 â€"" 3x to make it a perfect-square trinomial? Three-halves Nine-fourths 6 9.

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer

the answer is 13/48

step-by-step explanation:

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:

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
