How do you solve (2x + 8 )2 =64

Answer:

x = 12

Step-by-step explanation:

Write in a different way: 2(2x + 8) = 64
Apply the distributed property, so it now looks like this: 4x + 16 = 64
Subtract 16 from each side, so it now looks like this: 4x = 48
Divide each side by 4 to cancel out the 4 next to x. It should now look like this: x = 12

I hope this helps!

Answer:

a. 8 outcomes

b. Discrete Variable

c. See explanation below

Step-by-step explanation:

a.

Let N = No Offers made

Let Y = Offers made

The Expected outcome are as follows:

NNN, NNY, NYN, YNN, NYY, YNY, YYN, YYY

= 8

b.

Let x = number of offers made

X is said to be discrete if x can take values that are restricted to a defined or limited values

X is said to be continuous if x can take a range of values that is not restricted to any range(i.e. continuous)

Looking at the brief description above, we can conclude that x is discrete

c.

NNN, 0

NNY, 1

NYN, 1

YNN, 1

NYY, 2

YNY, 2

YYN, 2

YYY, 3

Where 0 to 3 represents number of offers at every instance

The diameter of the circle is needed. But to solve, you would simply multiply the diameter of the circle by pi (3.14).

Answer:

He have <u>15</u> action games and <u>24</u> sports games.

Step-by-step explanation:

Given:

Ryan has a mix of action and sports games for a total of 39 video games his action collection is three more than half his sports collection.

Now, to find the number of action games and sports games.

Let the sports games be $x.$

As, given his action collection is three more than half his sports collection.

Thus, the action games = $3+\frac{x}{2}$ .

Total number of video games = 39.

So, we set an equation to get the number of action games and sports games:

$x+(3+\frac{x}{2})=39$

$x+3+\frac{x}{2} =39$

<em>Subtracting both sides by 3 we get:</em>

$x+\frac{x}{2} =36$

$\frac{2x+x}{2}=36$

$\frac{3x}{2} =36$

<em>Multiplying both sides by 2 we get:</em>

$3x=72$

<em>Dividing both sides by 3 we get:</em>

$x=24.$

<u>The sports games he have = 24.</u>

Now, to get the action games we substitute the value of $x$ :

$3+\frac{x}{2}$

= $3+\frac{24}{2}$

= $3+12$

= $15.$

<u>The action games he have = 15.</u>

Therefore, he have 15 action games and 24 sports games.
