Answer:

(11 x - 20)/(x (x - 4)) = 11x-20/x^2-4x

Step-by-step explanation:

Simplify the following:

6/(x - 4) + 5/x

Put each term in 6/(x - 4) + 5/x over the common denominator x (x - 4): 6/(x - 4) + 5/x = (6 x)/((x - 4) x) + (5 (x - 4))/((x - 4) x):

(6 x)/(x (x - 4)) + (5 (x - 4))/(x (x - 4))

(6 x)/((x - 4) x) + (5 (x - 4))/((x - 4) x) = (6 x + 5 (x - 4))/((x - 4) x):

(6 x + 5 (x - 4))/(x (x - 4))

5 (x - 4) = 5 x - 20:

(5 x - 20 + 6 x)/(x (x - 4))

Grouping like terms, 6 x + 5 x - 20 = (6 x + 5 x) - 20:

((6 x + 5 x) - 20)/(x (x - 4))

6 x + 5 x = 11 x:

Answer: (11 x - 20)/(x (x - 4))

for the first term:

n= 1 there is 1 item

n=2 there are 2+1 = 3 items

n = 3 there are 3+2+1 = 3+2 = 6 items

n = 4 there are 4+3+2+1 = 4+6 = 10 items

We are adding the "n" term each time

n = 5 10+5 = 15

n= 6 15+6 = 21

n = 7 21+7 = 28

n = 8 28+8 = 36

There would be 36 items in the 8th step

PLZZZZZZ HELPPPPP

Answer:

(D)

Step-by-step explanation:

The graph shows the arm span lengths of the students, clearly we can see that the most of the students have arm span length in the initial points of the length.

Median = Middle frequency of the data. Here, median will be the length in the middle.

Mode = Most frequently occurring number in the data. Here the mode will be the length which most of the students has.

Clearly, most of the student has the length in the initial inches while the median will be in the middle.

Hence, mode will be less than the median.
