Answer:
x=13 degrees
Step-by-step explanation:
First, think of the remote interior angle theorem. So basically the remote interior angles that don't share a vertex with the exterior angle is the sum of the exterior angle. So that means ∠EBC+∠BEC=∠ECD. ∠ECD=64 degrees+90 degrees=154 degrees. ∠EBC is equal to 180 degrees minus 3x because line AD is a line so ∠ABE and ∠EBC are supplementary angles so basically they add up to 180 degrees. So the equation is (180-3x)+x=154. Simplify the equation and you should get x=13 degrees:)
The range of function is 
.
The answer is B.

Answer:
Step-by-step explanation:
<u>Check rational zeroes with synthetic division</u>
3 | 2 -7 -27 63 81
____<u> 6 -3 -90 -81</u>__
2 -1 -30 -27 | 0
-3 | 2 -1 -30 -27
____<u>-6_21_27</u>___
2 -7 -9 | 0
-1 | 2 -7 -9
____<u>-2_9</u>
2 -9 | 0
Thus, 
. We have one more zero left, which is solved through the equation 
by the Zero Product Property:
Therefore, all the zeroes of f(x) from smallest to largest are
