Answer:

x= $\sqrt{6}$

Step-by-step explanation:

subtarct 2 t the other side

2x^2=12

now divide 2 to 12

x^2= 6

now square root both sides

x= $\sqrt{6}$

thats the answer!

Answer:

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x²+2=14

Step 2: Subtract 2 from both sides.

2x²+2 −2 =14 −2

2x²=12

Step 3: Divide both sides by 2.

2x²÷ 2 =12 ÷ ²

x²= 6

Step 4: Take square root.

x= √ 6

x=6 or x=−6

The student council is hosting a drawing to raise money for scholarships. They are selling tickets for $8 each and will sell 900

andrew-mc [135]

Step-by-step explanation:

the probability that the ticket will win you 600 dollars * 1/1500 = 600/1500.

the probability that the ticket will win you 50 dollars is 50 * 5/1500 = 250/1500.

the probability that the ticket will win you 25 dollars is 25 * 20/1500 = 500/1500.

your expected value is -1 + 600/1500 + 250/1500 + 500/1500 = -.1.

the average loss for each dollar that is bet is equal to 10 cents.

hope this helped

first polygon

ext. angle=180°-120°

=60°

$ext \: ang = \frac{360}{n}$

n=360°/60°

n=6

second polygon

n=2(6)=12

ext. ang= 360°/n = 360°/12° = 30°

int. ang = 180°-30°= 150°

answer is C

Determine the distance between the following two points. (round to the nearest hundredths)

padilas [110]

Answer:

$d=7.07$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Simply plug in the 2 coordinates into the distance formula to find distance d:

$d=\sqrt{(3-(-2))^2+(-4-1)^2}$

$d=\sqrt{(3+2)^2+(-5)^2}$

$d=\sqrt{(5)^2+25}$

$d=\sqrt{25+25}$

$d=\sqrt{50}$

$d=5\sqrt{2}$

$d=7.07$

Adding integers (+6)+(+2)

noname [10]

Answer:

$6 + 2=8 \\so... +2 + +6 = +8\\$

Step-by-step explanation:

So the thing about adding of integers is that is both nos. are positive then you can simply add it and same with negative too.But with negative and positive we should subtract but that is for later.Luckily we have 2 positive integers so we do it like this:

+6 is the same as 6 and +2 is the same as 2 so we...

rule:add the numbers and add the sign.

$6 + 2=8\\so... +2 + +6 = +8$
