The property here is the Commutative Property of Addition.
Answer:
(x-3)(x-2)
Step-by-step explanation:
x^2-5x+6
x^2-2x-3x+6
x(x-2)-3(x-2)
(x-3)(x-2)
answer is C. 10
triangle is a right triangle
so you can use the Pythagorian theorem
and
2 out of the 3 sides are equal
so 2 sides are 5√2
5√2 = √5*5*2 = √50
Pythagorian theorem is
a^2 + b^2 = c^2
so
√50^2 + √50^2 = c^2
50 + 50 = c^2
100 = c^2
√100 = c
c = 10

and surely you know what that is
The center is located at 0,0 and the radius is 5.
