(BRAINLIEST) After the fraction x plus 1 all over 3 minus the fraction x plus 2 all over 2 x have been combined using the least common denominator of 6x, what is the numerator? (6 points) 2x2 − x + 2

−2x2 − x + 3

2x2 − x − 6

−x2 + x + 3

step-by-step explanation:

the answer is 128

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:

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
