Answer:
10x² - 9x
Step-by-step explanation:
(10x² - 10x - 6) + (x + 6)
10x² - 10x - 6 + x + 6
10x² - 9x - 6 + 6
10x² - 9x

Answer:
Step-by-step explanation:
Vertical Angles are congruent, so set the two expressions equal to each other:
[x + 30]° = [3x - 18]°
-[3x]° - [3x]°
___________
−18° = 30° - [2x]°
- 30° - 30°
____________
−48° = [−2x]°
____ ___
−2° −2°
[Plug this back into both expressions to get both <em>m</em>∠<em>N</em> and <em>m</em>∠<em>M</em> at 54°.]
