the image of δabc after a reflection across is δa'b'c'.

which triangle must be a right triangle and why?

a. δa'b'c' is right because it is the image of δabc.
b. δadc is right because aa' intersects ac at a.
c. δbcc' is right because b lies of the line of reflection.
d. δbgc is right because eg< --> is congruent to cc'.

it is probably the graph on the bottom right.

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."

good job you smart son of a gun you are smarter that einstein. 7
