Answer:
8.9m
Step-by-step explanation:
area of square is side length squared so
=8.944
for all positive integers (like n = 1, 2 or 5) the conjecture holds true but not for negative values like if n = -3 then the result will not become positive, because:

which is not positive.
Answer:
4.9 hours
Step-by-step explanation:
set it up as a proportion 1625/2.5 = 3185/x. then solve
Answer:
3. 5cm

Step-by-step explanation:
3. the hypotenuse C squared = side A squared + side B squared. So 3 × 3=9 and 4 × 4 =16 therefore 9 + 16 =25 and the square root of 25 = 5.
4. In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.
<h3>Hope it is helpful....</h3>

Why?
We can find the perimeter of any triangle adding the length of its sides. Since we are given 3 points, we need to calculate the length of the three sides of the triangle, and then add them to know the perimeter of the triangle.
Let be the points:
A(-3,-1)
B(-1,2)
C(6,1)
<h3>
- Distances</h3>
From A to B:

From A to C:

From B to C:

Now, calculating the perimeter, we have:
