Answer:

The answer is D. 72 m

Step-by-step explanation:

To find the answer, you need to know what the original perimeter is. Say the perimeter is 6+6+3+3. You multiply all of those numbers and you get 24+24+12+12. Add those together and you get 72.

How can i show my work for 2x-4= -10+x

Let me help you with that :)

2x - 4 = - 10 + x (we transfer the x from the right side, and transfer the  - 4 from the left side)

2x - x = - 10 + 4 (we calculate this)

x = -6

And that is the answer; x = - 6 :)

Studentka2010 [4]

The median, upper and lower quartiles of the data set are:

Lower Quartile = 46

Median = 49

Upper Quartile = 90

<h3>What is the Median?</h3>

The center value or middle value of a data set is the median.

<h3>What are the Upper and Lower Quartiles?</h3>

Upper quartile (Q3) is the center or middle data point of the second half of a data set.

Upper quartile (Q3) is the center or middle data point of the second half of a data set.

Order the data set given as:

32, 46, 49, 49, 77, 90, 96

Lower Quartile = 32, (46), 49, 49, 77, 90, 96 = 46

Median = 32, 46, 49, (49,) 77, 90, 96 = 49

Upper Quartile = 32, 46, 49, 49, 77, (90,) 96 = 90
