Rewrite 6x^2-24=0 as 6(x^2-4)= 0 and then factor x^2-4:

6(x-2)(x+2)= 0. The solutions are {-2,2}.

Answer:

Adam

Step-by-step explanation:

Speed is calculated with the formula distance over time.

Convert all measurements to the same unit: ft/s.

Speed of Frank:

d/t

=11/s

Speed of Emily:

d/t

=86/10

=8.6/s

Speed of Adam:

There are 5280 feet in a mile.

d/t

=5280/388

=13.6/s

Speed of Noah:

There are 60 seconds in a minute.

d/t

=600/60

=10/s

Adam runs the fastest because 13.6 > 11 > 10 > 8.6.

A bag contains 6 red tiles, 8 blue tiles, and 6 green tiles. A tile is drawn, the color recorded, and then the tile placed back

tester [92]

Answer:

9 red tiles

Step-by-step explanation:

Total number of tiles: $6+8+6=20$

Total number of red tiles: $6$

Probability of getting red in one draw: $\frac{6}{20}=0.3$

This means that you would expect to get red $0.3$ or 30% of the times.

Hence, when you draw tiles 30 times from the bag, you would expect red to be picked 30% of 30 times. This is:

$0.3*30=9$

So, you would expect to draw a red tile from the bag 9 times.
