Answer:
the formula is (n-2)180 degrees
so its 7020
The answer is B. 8x+6. You multiple 3 and x+4 then combine like terms
Answer:
x= -21
Step-by-step explanation:
6/7x=-18
divide both sides by 6/7
------------
x= -21

Step-by-step explanation:

Please, see the offered decision:
1) common equation for lines is y=kx+b. If k₁=k₂ (for line 1 and line 2) ⇒ 'line 1' || 'line 2'.
2) for line 3x+5y=6 k= -3/5. It means (according to item 1) for unknown line k is the same (-3/5).
3) using points (0;3) it is easy to find parameter b (x=0, y=3) via y=kx+b:
3=0*(-3/5)+b ⇔ b=3.
4) finaly (k=-3/5; b=3):
