In a rectangle, lengths of diagonals are equal. If you draw the rectangle, you can see that KM and LN are diagonals, so they must be equal:
KM = LN
KM = 6x + 16
LN = 49
6x + 16 = 49
6x = 49 - 16
6x = 33
x = 33/6
x = 5.5
Answer:
Since there are 60 seconds in one minute, we can write this as 146,000 inches per minute. Since there are 60 * 60 = 3600 minutes in one day, we can write it as 525,600,000 inches per day. Since there are about 63360 inches in one mile, the answer is about 8295 miles per day.
Number of proper subsets = 2^number of elements- 1
= 2^n - 1
No of elements = 4
2^4-1 = 16-1 = 15
