the length of a rectangle is 2 inches less than twice its width. If the perimeter of the rectangle is 74 inches, what is the are
schepotkina [342]
If the width is w and the length is l, then 2w-2=l and 2w+2l=72 (using the perimeter equation). Plugging 2w-2 in for l, we get 2w+(2w-2)*2=72 and 6w-4=72. Adding 4 to both sides, we get 6w=76. After that, we divide both sides by 6 to get 74/6=w. Since l=2w-2=136/6, we get (136/6)(74/6)=656.75=area

creativ13 [48]

Answer:

Step-by-step explanation:

The given data is 11, 77, 35, 5, 76, 34, 89, 92, 22

The total number of items in the data is 9. The width of each class interval would be gotten by dividing the difference between the minimum and maximum items in the data by the number of class intervals. From the information given,

Minimum item = 5

Maximum item = 92

Difference = 92 - 5 = 7

Class width = 87/10 = 8.7

By approximation, it is closest to 10

Therefore, the appropriate class group is 0 to 10
