Answer:
In triangle ABC one side equal
and two sides equal 
Step-by-step explanation:
We are given a prism whose base is square with sides 8 in and height 12 in.
If we take cross section through vertices A, B and C
We will get a cross section as triangle.
In triangle ABC, sides are AB, BC and AC
AB is diagonal of top square whose side 8 in.

AC is face diagonal of front face.

BC is face diagonal of right face.

AC=BC≠AB
Hence, In triangle ABC one side equal
and two side equal 
To find the solutions to the system, we need to find exactly when one expression is equal to the other. We can do this by setting both of the right sides equal to each other, so that

Subtracting x+6 from either side, we find

factoring out an x+6:


The x-coordinates of our solutions will therefore be 6 and -6. Since the question only asks for the <em>x-coordinate</em> of the midpoint, we simply need to find the number exactly halfway between 6 and -6, which is 0.
No association because there are no negatives and the dots are scattered out along the graph
Answer:
(-1, 2)
Step-by-step explanation:
If we have a point (h,k) and it is rotated 90 degrees clockwise, the resulting point will have coordinates (k, -h).
So, basically the y coordinate becomes the x coordinate and x coordinate becomes the NEGATIVE of the y coordinate.
The point to rotate is (-2, -1), so after 90 degree clockwise rotation, it will become:
(-1, -(-2))
= (-1, 2)
This is the answer.
