Answer:
16.24 Units
Step-by-step explanation:
The perimeter of the triangle is the sum of the length of the sides of the triangle. Given the points on the vertices, the length of each side may be found using the formula
Length = √(x2 - x1)^2 + (y2 - y1)^2
Considering the pair (-1, 2), (3, 1), the length of that side
= √(3 -- 1)^2 + (1-2)^2)
= √(16 + 1)
= √17 units
Considering the pair (-1, 2), (7, 2), the length of that side
= √(7 -- 1)^2 + (2-2)^2)
= √(64)
= 8
Considering the pair (3, 1), and (7, 2), the length of that side
= √(7 - 3)^2 + (2 - 1)^2
= √(16 + 1)
= √17
Hence the perimeter of the triangle
= √17 + 8 + √17
= 4.12 + 8 + 4.12
= 16.24 Units

Answer:
This question is impossible
Step-by-step explanation:
There is no answer.
A quotient means division, so you can get rid of the third and fourth choices. It says "opposite" so that means negative.
The answer is the second choice: 
Answer:
62 miles per hour speed if you drove 325 miles in 5 1/4 hours
Step-by-step explanation:
Using formula:
As per the statement:
if you drove 325 miles in 5 1/4 hours
⇒
miles
and
Time = 
hours
Then by above formula we have;
miles per hour
Therefore, 61.90 ≈ 62 miles per hour speed if you drove 325 miles in 5 1/4 hours
