Answer:
10
Step-by-step explanation:
length of 1 side is sqrt(10), square it and it becomes trivial
Answer:
(13, -6.5)
Step-by-step explanation:
Find the distance between points J and the midpoint, which is 8.5 for x-coordinates and 2.5 for y-coordinates.
Add these values to the midpoint coordinates to get the coordinates of point K
4.5 + 8.5 = 13
-8.5 + 2.5 = -6.5
The coordinates of point K are (13, -6.5)
we know that
A polynomial in the form
is called a sum of cubes
so
Let's verify each case to determine the solution
<u>case A)</u> 
we know that




-------> is not a perfect cube

therefore
the case A) is not a sum of cubes
<u>case B)</u> 
we know that
-------> is not a perfect cube



-------> is not a perfect cube

therefore
the case B) is not a sum of cubes
<u>case C)</u> 
we know that
-------> is not a perfect cube




therefore
the case C) is not a sum of cubes
<u>case A)</u> 
we know that





Substitute


therefore
<u>the answer is</u>
is a sum of cubes
u can you download the gauthmath app i promise it's very helpful :)
thanks me later (. ^ ᴗ ^.)
