-5k - 10

Step-by-step explanation:

Given:

-k + 2 ( -2k - 5)

Open parenthesis

-k - 4k - 10

Simplify like terms

-5k - 10

Answer is

(Choice B) B -5k-10−5k−10minus, 5, k, minus, 10

-k + 2 ( -2k - 5) is equivalent to -5k - 10

answer:

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:
