2x + 11 = 5
If a and b are the solutions to the equation above, what is the value of |a – b| ?

x = 3

Step-by-step explanation:

2x + 11 = 5

- 11          -11

2x/2         6

x        =     3

answer: 2 and 1

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:
