3x^2 + 9x + 6 = 0
3x^2 + 3x + 6x + 6 = 0
3x(x + 1) + 6(x + 1) = 0
(3x + 6)(x + 1) = 0
3x + 6 = 0 and x + 1 = 0
3x = -6 and x = -1
x = -2 and x = -1
Answer:
-18/3x - 9
Step-by-step explanation:
-9(2/3x + 1)
Expand.
-18/3x + -9
C = 2×pi×r
72 = 2×pi×r
so r = 36/pi
DE = 30deg×36/pi
DE = (pi/6)×(36/pi) = 6cm
