Answer:
k= -2
Step-by-step explanation:
you are dividing the x by -2 each time
Angle ADC and EDG are congruent(vertical angles)
Same side interior angles are =180
2x+4x-30=180
6x-30=180
6x=210
x=35
CDG is congruent to DGH(alternate interior)
4x-30
4(35)-30
140-30
=110
Answer:
-9x
Step-by-step explanation:
-7x + -2x
Factor out the x
x(-7-2)
x(-9)
-9x
