Find the product. (a - 8)(a + 2) A. 2a - 6 B. a2 - 16 C. a2 - 10a + 16 D. a2 - 6a - 16

  D.  a^2 - 6a - 16

Step-by-step explanation:

The product is found using the distributive property.

  (a -8)(a +2) = a(a +2) -8(a +2)

  = a^2 +2a -8a -16

  = a^2 -6a -16 . . . . . matches choice D

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

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:
