Answer: The right hand limit is 4
-------------------------------
Start on the right side of the value x = 2. In other words, start at some value larger than 2, say x = 4. Starting at x = 4, move closer to x = 2. Move as close as you can. The closer x gets to 2, the closer y gets to 4. You'll never actually get to x = 2 or y = 4 because of the hole. However, the right-hand limiting value is 4 assuming you can keep getting closer and closer.
Note: if you approach x = 2 from the left side, you arrive at a different y value So this suggests that overall, the limit at x = 2 doesn't exist. But the right hand limit (RHL) does exist as described above.
3 consecutive even numbers : x, x + 2, x + 4
x + x + 2 + x + 4 = 90
3x + 6 = 90
3x = 90 - 6
3x = 84
x = 84/3
x = 28...thats gonna be the smallest
x + 2 = 28 + 2 = 30
x + 4 = 28 + 4 = 32
Answer:

Step-by-step explanation:
Given:
After lunch the friends walked 6 3/4 miles before arriving at the end of the trail.
The trail is 14 1/8 miles long.
Question asked:
How long did the friends walk before lunch ?
Solution:
Let the friends walk before lunch in miles = 
As total length of trail is given
, we can conclude:
Total length of trail = The friends walk before lunch in miles + The friends walk after lunch in miles

Subtracting both side by 

Taking LCM of 4 and 8 ,we get 8

Therefore, the friends walk before lunch is
.
the square root of 300 is 17
