Answer:
C (x = 2)
Step-by-step explanation:
Since x is a non-negative number, A and B are eliminated.
This leaves C and D.
C: x = 2,
2 + 3 < 2^2
5 < 4 is false.
So C would be a counterexample.
Hope this helps!
Answer:
First blank: 11 Second blank: 12
Step-by-step explanation:
Since this is a parallelogram AB is parallel to DC and AD is parallel to BC.
Another thing the image includes is the lengths from the points, the opposing points have equal distances from the midpoint.
Uhh, answer choices?
In any case, since
is inscribed in a semicircle, it is a right triangle (due to the inscribed angle theorem). Thus, by the Pythagorean theorem,
Now, the circumradius of a right triangle (the radius of the circle passing through all three of its vertices) is simply half its hypotenuse, so 
The picture wouldn't fit but the first step was to multiply the denominators by 8
the answer is -11/2
