Andre tried to solve the equation LaTeX: \frac{1}{4}\left(x+12\right)=21 4 ( x + 12 ) = 2 , but he made a mistake. In which step was his mistake? A. Rewrite the equation

LaTeX: \frac{1}{4}\left(x+12\right)=21 4 ( x + 12 ) = 2

B. subtract 12 from both sides

LaTeX: \frac{1}{4}x=-101 4 x = − 10

C. multiply both sides by 4

LaTeX: x=-40x = − 40

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:

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.
