Solve the following equation:
x + 2 - 3x = - (x + 2)
o
x = 4/3
o
x=4
o
x= -4/5
o
no solution

B will be your answer :)

Step-by-step explanation:

x + 2 - 3x = -(x + 2)

x + 2 -3x = -x - 2

2 + -2x = -x - 2

-x = -4

x = 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:
