Answer:
3,-3
Step-by-step explanation:
g(3)= (3)³+6(3)²-9(3)-54
= 27+54-27-54
=81-81
= 0
g(-3) = (-3)³+6(-3)²-9(-3)-54
= -27+54+27-54
= 27-27
= 0

Answer:
Step-by-step explanation:
The angles of a linear pair are supplementary. That is, they total 180°. The angle marked x° and the one marked 72° are a linear pair:
x° +72° = 180°
x = 180 -72 = 108 . . . . . . . divide by °, subtract 72
__
Vertical angles are congruent. Angles y° and 72° are vertical angles, so ...
y = 72
__
Angles z° and 72° together make a right, which has a measure of 90°.
z° +72° = 90°
z = 90 -72 = 18 . . . . . . . divide by °, subtract 72
__
(x, y, z) = (108, 72, 18)
_____
<em>Additional comment</em>
Angles 72° and x° form a linear pair, as do angles x° and y°. That is, angles 72° and y° are both supplementary to angle x°. Angles that are supplementary to the same angle are congruent. This will be the case for any vertical angles: they are supplementary to the same angle.
The answer you are looking for would be 2.
This can be found by solving with PEMDAS. First, you do the 4^2 (4*4), which equals 16. Next, you multiply 16 by 7, to get 112. Then, you'd divide 112 by 8. This gives you 14. Finally, subtract 12 from 14 to get your final answer of 2.
I hope this helps!
