Which of the following sets could the lengths of the sides of a scalene triangle? A. a = 5, b = 6, c = 6
B. a = 3, b = 5, c = 7
C. a = 2, b = 3, c = 5
D. a = 3, b = 3, c = 6

B.a=3 ; b=5 ; c=7

or

C.a=2 ; b=3 ;c=6

all scalene sides are not equal

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
