Answer:

3x6 = 729x when ever a number has an exponnet yo have to multiply the main number to itself as many times as it says.

So in this case you had to multiply 3 by itself(3) 6 times would be

(3x) x (3x) x (3x) x (3x) x (3x) x (3x) = 729x. And of course bring the variable.

x2 So when theres a varible that is by itself for example (x) you always add a 1 in front of it. so in this case x2 would be 1x2. 1 times itself(1) 2 times would be. (1x) x (1x) = 1x

729 smaller cubes would fit inside the larger cube.

S the interquartile range of this data?
Ray Of Light [21]

We have been given the 5-number summary of a box plot that represents Coins in Collection. The five-number summary from left to right is 7, 16, 30, 36, 38.

We are asked to find the inter-quartile range of the given data.

We know that interquartile range is difference of upper quartile and lower quartile.

We know that the 5-point summary represents the lower data point, lower quartile, median, upper quartile and upper data point respectively.

We can see from our given 5 point-summary that lower quartile is 16 and upper quartile is 36.

\text{Interquartile range}=\text{Upper quartile}-\text{Lower quartile}

\text{Interquartile range}=36-16

\text{Interquartile range}=20

Therefore, the interquartile range of the given data is 20 and last option is the correct choice.

Solve the system of linear equations by elimination. <br> 9x−2y=34 <br> 5x+2y=−6
slava [35]

Answer:

x = 2

y = -8

Step-by-step explanation:

9x−2y=34 -------------------(I)

5x+2y=−6 -------------------(II)

Add equation (I) & (II) and so y will be eliminated and we could find the value of x.

(I)      9x -  2y = 34

(II)     <u>5x  + 2y = -6</u>   {add}

       14x         =   28

                 x = 28/14

x = 2

Plug in x = 2 in equation (I)

9*2 - 2y = 34

18 - 2y = 34

     -2y = 34 - 18

    -2y = 16

        y = 16/-2

        y = -8
