Answer:
12x-1
Step-by-step explanation:
step 1: (2 • (3x - 5)) + 3 • (2x + 3)
step 2: 2 • (3x - 5) + 3 • (2x +3)
final result = 12x-1
Answer:
the answer is b
Step-by-step explanation:
Sin 20° · sin 40° · sin 80° = 1/2 ( cos 20° - cos 60° ) · sin 80° =
= 1/2 ( cos 20° sin 80° - cos 60° sin 80° ) =
= 1/2 ( (sin 100° + sin 60°)/2 - 1/2 sin 80° )= ( sin 100° = sin 80° )
= 1/2 · ( 1/2 sin 60° ) = 1/4 sin 60° = √3 / 8
sin 60° = √ 3/2
√ 3 / 2 · √ 3 / 8 = 3/16 ( correct )
