When (2x3 + 3x2 - 7x) is subtracted from (10x3 + 7x2 - 7) the result is

8 3 + 4 2 + 7 − 7

Step-by-step explanation:

Distribute

(103+72−7)−1(23+32−7)

(103+72−7)−23−32+7

Eliminate redundant parentheses

(103+72−7)−23−32+7

103+72−7−23−32+7

Combine like terms

103+72−7−23−32+7

83+72−7−32+7

Combine like terms

83+72−7−32+7

83+42−7+7

Rearrange terms

83+42−7+7

83+42+7−7

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:
