(6x -8)(2x -3)

B) 12x2 + 24
U) 70x
L) 8x2 - 21x + 11
E) 12x2 -34x + 24

E) 12x^2 - 34x +24

Step-by-step explanation:

6x times 2x Is 12x^2

6x times -3 = -18x

-8 times 2x = -16x

-8 times -3 = 24

combine terms and you get the answer

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:
