To find the perimeter of a triangle with corners at (5, 2), (2, 7), and (1, 4), you need to calculate the distance between each pair of points and then add them together.
The distance formula between two points (x1, y1) and (x2, y2) is given by:
Distance = √((x2  x1)^2 + (y2  y1)^2)
So, calculate the distances between:

(5, 2) and (2, 7)

(5, 2) and (1, 4)

(2, 7) and (1, 4)

Distance between (5, 2) and (2, 7): √((2  5)^2 + (7  2)^2) = √(9 + 25) = √34

Distance between (5, 2) and (1, 4): √((1  5)^2 + (4  2)^2) = √(16 + 4) = √20

Distance between (2, 7) and (1, 4): √((1  2)^2 + (4  7)^2) = √(1 + 9) = √10
Now, add these distances together to find the perimeter: Perimeter = √34 + √20 + √10

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
