You need to factor the numerator and denominator...
(2x^2+4x-2x-4)/(2x^2-2x-2x+2)
(2x(x+2)-2(x+2))/(2x(x-1)-2(x-1))
((2x-2)(x+2))/((2x-2)(x-1)) so the (2x-2)s cancel out leaving
(x+2)/(x-1)
Answer:
∠8 = 40°, ∠6 = 50°, ∠9= 140°
Step-by-step explanation:
∠8 = 40° (vertically opposite angles are congruent)
now, using angle sum property of triangles
∠6 + 90° + 40° = 180°
∠6 = 180° - 130°
∠6 = 50°
and, using exterior angle property,
50° + 90° = ∠9 = 140°
3.12/.52=6
