The rectangle below has an area of x^2-7x+10square meters and a width of x - 5 meters. What expression represents the length of
jolli1 [7]

Answer:

L = (x - 2) meters

Step-by-step explanation:

The area of the rectangle = (x² - 7x + 10) m²

The width = (x - 5) m

length = ?

Area of a rectangle = length × width

x² - 7x + 10 = L(x -5)

note L = length

divide both sides by (x-5)

(x² - 7x + 10)/(x - 5) = L

L = x² - 7x + 10 / (x -5)

Factorize x² - 7x + 10

find the numbers you can multiply to give you 10 and also add to give you -7

The numbers are -2 and -5. Therefore,

x² - 2x - 5x + 10 = 0

x(x - 2) - 5(x - 2) = 0

(x-5)(x-2) = 0

Let us go back to our division

L = x² - 7x + 10 / (x -5)

x² - 7x + 10 = (x-5)(x-2)

L = (x-5)(x-2) / (x -5)

L = (x - 2) meters

Which data set COULD NOT be represented by the box plot shown? A) {13, 5, 8, 8, 6, 10, 15, 12, 4, 13, 11} B) {2, 10, 13, 7, 9, 5
siniylev [52]

Answer:

B

Step-by-step explanation:

From the box plots shown above:

The lowest number is 4

The highest number is 15

Therefore, the values in each boxes must lie between {4,15}.

In option A the values in the box include: {13,5,8,8,6,10,15,12,4,13,11}. The values of this data lies between 4 and 15 which makes it correct.

In the second option(B) the values in the boxes include: {2,10,13,7,9,5,15,12,7,13,11}.

The value 2 is not present in the interval, therefore the set of data is wrong.

In option C the values in the box include: {15,13,6,7,10,8,11,13,13,6,4}.

The values of this data lie between the interval of 4 and 15 which makes it correct.

In option D, the values in the box include: {4,13,6,7,15,12,11,10,5,13,9}·

The values of this data lie between the interval of 4 and 15 which makes it correct.
