Kai lives 3 kilometers from school, Brea lives 30,000 meters from school, and Cal lives 30,000 centimeters from school. Which statement about these distances is true?
A. Kai lives the farthest from school
B. Brea lives the closest to school
C. Cal lives farther from school than Kai
D. Brea lives the farthest from school
MARKING BRAINLIST IF CORRECT!! :)

D. Brea lives the farthest from school

Step-by-step explanation:

The easiest way to go about this is to get them all to the same unit. Let's do meters :)

3 kilometers = 3,000 meters (Kai)

30,000 centimeters = 300 meters (Cal)

and then of course 30,000 meters is already in the correct unit (Brea)

Given all of this, you can easily tell that the answer is D

- 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
