Answer:

B) -5, 5, -7, 7           

Step-by-step explanation:

3x² - bx + 2

factor:

(3x - 2 )(x - 1) = 3x² - (5)x + 2      so 5 does work

(3x - 1 )(x - 2) = 3x² - (7)x + 2      so 7 does work

(3x + 2 )(x + 1) = 3x² + 5x +2    =    3x² - (-5)x + 2      so -5 does work

(3x + 1 )(x + 2) = 3x² + 7x + 2   =    3x² - (-7)x + 2      so -7 does work

Olives solar powered scooter travels at a rate of 30 miles per hour. What equations can she use to calculate her distance with r
USPshnik [31]

Answer:

D = 30*T, where D is the distance in miles and T is the time in seconds

Step-by-step explanation:

The speed of the powered scooter is 30 miles per second, so for each second, her distance will be 30 miles.

With that information, we can formulate an equation that shows her distance with relation to time:

Let's call her distance D, and the time she is traveling T

if in one second she travels 30 miles, in T seconds she will travel 30*T miles, and that is the distance she travelled, so the equation is:

D = 30*T.
