X+3 +x+2 is it equivalent to 2x + 5 when x= 4 A. Equivalent 13 = 13
B. Not equivalent 13 ≠ 13
C. Not equivalent 13 ≠ 29

what is the question?

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:

i think it would be c
