Most hard drives are divided into sectors of 512 bytes each. Our disk has a size of 16 GB. Fill in the blank to calculate how many sectors the disk has.

33,554,432 sectors

Step-by-step explanation:

-We first convert both sizes to a uniform measure(both to be in bytes or gigabytes).

-We convert the drive size into Bytes:

#We then divide the Drive size by the sector size to get the number of sectors.

-Let X be the number of sectors:

Hence, the disk has 33,554,432 sectors.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
