(4y+8) ÷6-12 which is the variable?

what is the sum?

what is the quotient?

which is the coefficient?

variable- y  this is it can vary on what number it is

sum- 4y+8

quotient- (4y+8) / 6

coefficient- 4

simplified it would be y+2-6-12

the answer to this problem is y+4

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:
