2x-18 is the simplified expression
Answer:
see explanation
Step-by-step explanation:
Under a clockwise rotation about the origin of 90°
a point (x, y ) → (y, - x ) , then
R(2, - 1 ) → R'(- 1, - 2 )
S(4, 0 ) → (0, - 4 )
T(1, 3 ) → T'(3, - 1 )
The correct answer to this question is:
Diameter - B) a segment <span>between two points on a circle that passes through its center radius
</span>
Circumference - <span> F) the distance around a circle

concentric circles - </span><span>D) Two circles that share the same center.
</span><span>
arc - </span><span>A) a piece of the circumference of a circle circumference.</span>
I believe it is 2c^8, but I'm not sure.
Answer:
A is the correct answer
Step-by-step explanation:
Mathematically if we have lengths a, b and c
For a triangle to occur, let us say that the third side is c
then a + b must be greater than or equal to c
Hence c must be equal to (4 + 8) or greater than (4 + 8)
With the options given , A is the correct answer
