X=1

x-1/(x-3)(x+1)=0
Multiply both sides by the denominator— in this case, (x-3)(x+1).
x-1=0
Add 1 to both sides.
x=1

A park has a 333 meter (\text{m})(m)left parenthesis, start text, m, end text, right parenthesis tall tether ball pole and a 6.8
dybincka [34]

Answer:option B & D are correct

Step-by-step explanation:

Given options are  

                                             A              B          C             D           E        

Tether ball pole shadow      1.35         1.8        3.75        0.6       2

Flagpole shadow                  3.4          4.08      8.35       1.36      4.8

Ratio of corresponding height & shadows  should be same

3 meter tall tether ball pole and a 6.8 tall flagpole

=> Ratio  = 6.8/3    = 68/30  = 34/15  

A    - 3.4/1.35 =   340/135     ≠ 34/15( 306/135)

B  -  4.08/1.8  = 408/180   =  34/15  = 34/15  ( Correct option)

C    8.35/3.75  = 835/375  =  167/75   ≠ 34/15( 170/75)

D  1.36/0.6  = 136/60   =  34/15  = 34/15   ( Correct option)

E  4.8/2  = 48/20   =  12/5   = 36/15    ≠ 34/15

option B & D are correct

Please help ASAP first to answer correctly gets brainlyist

Median means middle. How you solve this is by first putting the numbers in order from least to greatest:

36  41   43   45  46  48  48  51  51  52

Now that it is in order in each "level" take away the smallest and largest number until you get to the middle

36 41   43   45  46  48  48  51  51 52

      41   43   45  46  48  48  51 51

             43   45  46  48  48  51

                    45  46  48  48

                            46  48

Now this is a bit tricky because there isn't one number to signify the exact middle. When you have two numbers left you must take the mean of those two numbers. This means that you add the two numbers left and then divide the answer by 2:

46 + 48 = 94

94 ÷ 2 = 47

Hope this helped!
