6 0

Answer:

B  x=3

Step-by-step explanation:

12x = 2x^2 +18

Divide by 2

12x/2 = 2x^2/2 +18/2

6x = x^2 +9

Subtract 6x from each side

6x-6x = x^2 -6x+9

0= x^2 -6x+9

Factor

What 2 numbers multiply to 9 and adds to -6

-3*-3 = 0

-3+-3 =-6

0= (x-3) (x-3)

Using the zero product  property

x-3 =0   x-3 =0

x=3   x=3

Presume we have this sack of marbles. There are 4 green marbles, 3 red marbles, 2 blue marbles, and 1 yellow marble.
aleksley [76]

Answer:

There is a 33.3% chance you will pull a red marble after pulling a blue one.

Step-by-step explanation:

There are a total of 10 marbles in the sack. A blue marble is removed from the bag without being replaced, leaving 9 in the sack. 3 of the marbles left are red. To find the probability of pulling a red marble, we divide the number of red marbles by the number of total marbles.

3/9 = 1/3 = 0.333 = 33.3%
