Answer:The third one is!!
Step-by-step explanation:
The commutative property of addition says that changing the order of addends does not change the sum. Here's an example: 4 + 2 = 2 + 4 4 + 2 = 2 + 4 4+2=2+4
Answer:
No
Step-by-step explanation:
In a right angle triangle, based on Pythagoras theorem, the sum of the squares of the adjacent and opposite sides must equal to the square of the hypotenuse.
The hypotenuse is the side with the longest length:
H² = O² + A²
if from the given lengths;
H = 11, O = 9 and A = 6
Let us see if this is true;
H² = 9² + 6²
H² = 81 + 36
H² = 117
But H², 11² = 121 and this is not true
The triangle is not a right angled one.
Answer:

Step-by-step explanation:
First find the midpoint of the segment from (2, -6) to (-4, -16)
((2 - 4)/2, (-6 - 16)/2)
(-2/2, -22/2)
(-1, -11) is the midpoint and is the center of the circle
Now find the distance between the 2 given points and divide by 2 to get the radius of the circle
d = 
= 
= 
= 
r =
/2
= 136/4 = 34
Equation of circle with center at (-1, -11) and radius =
is
