I get:
24 = 3x-12
add 12 to both sides

36 = 3x

divide each side by 3 and you will get 12

3x - 12 = 24
add 12 to both sides
3x = 36
Divide both sides by 3
x = 12

To start a board game,the player who rolls two sixes gets to go first. What is the probability that a player will roll two
kati45 [8]

There is a 1/36 or a ~2.8% chance that a player will roll two sixes. Because the dice is cubed, the player will have a 1/6 probability of rolling a six one time. Because the player needs to get six 2 times in a row, you would simply need to multiply 1/6 by itself twice(1/6•1/6 or 1/6^2) which equals 1/36.

WARRIOR [948]

Answer:

2\,(x-1)^2=4

which is the first option in the list of possible answers.

Step-by-step explanation:

Recall that the minimum of a parabola generated by a quadratic expression is at the vertex of the parabola, and the formula for the vertex of a quadratic of the general form:

y=ax^2+bx+c

is at   x_{vertex}=\frac{-b}{2\,a}

For our case, where a=2\,\,, b=-4\,\,,\,\,and \,\,c=-2  we have:

x_{vertex}=\frac{-b}{2\,a}\\x_{vertex}=\frac{4}{2\,*\,2}\\x_{vertex}=1

And when x = 1, the value of "y" is:

y(x)=2x^2-4x-2\\y(1)=2(1)^2-4(1)-2\\y(1)=2-6\\y(1)=-4\\y_{vertex}=-4

Recall now that we can write the quadratic in what is called: "vertex form" using the coordinates (x_{vertex},y_{vertex)of the vertex as follows:

y-y_{vertex}=a\,(x-x_{vertex})^2

Then, for our case:

y-(-4)=2\,(x-1)^2\\y=2\,(x-1)^2-4

Then, for the quadratic equal to zero as requested in the problem, we have:

y=2\,(x-1)^2-4=0\\2\,(x-1)^2-4=0\\2\,(x-1)^2=4

Need help on polynomials
kkurt [141]
Follow these steps and you should get your answer its not the same questions but it should help
The answer to the problem is as follows:

These two polynomials are 5x^2 + 3x + 5 and 3x^2 +2x + 2:

Subtracting the second expression from the first:

<span>5x^2 + 3x + 5
- (3x^2 +2x + 2)
</span>____________
<span>2x2 + x + 3  <------------- The difference

Abe and Ben each have a certain number of dollars. If Abe gives Ben $5 then Abe and Ben will have the same number of dollars. If
11111nata11111 [884]
A = 5 + B
A + 5 = 2B

Let's get one of the variables on one side.

A = 5 + B
A = 2B - 5

By the transitive property

5 + B = 2B - 5

Solve for B.

5 = B - 5
10 = B

Use 10 = B in an earlier equation to find A.

A = 5 + B
A = 5 + 10
A = 15

Abe has 15$ and Ben has 10$.
