3x-8 = 8x+4
subtract 3x from each side
-8 = 5x+4
subtract 4 from each side
-12 = 5x
divide -12 by 5 to get x
x = -12/5 = -2.4

Answer:
A) The sequence is geometric because the sequence is increasing by a factor of 2 being multiplied to each term, when ascending from left to right.
B) 
C) 
Step-by-step explanation:
The sequence is multiplying each term by a factor of 2.
5*2=10
10*2=20
20*2=40

Answer: Sin0 = 8/8.5
Step-by-step explanation: What we have is a right angled triangle, with two sides given and one angle which is the reference angle (unknown angle).
The Sine of the angle is calculated as
Sin0 = opposite/hypotenuse
We have the opposite side (facing the reference angle) as 8 units and the hypotenuse (facing the right angle unknown), which we shall label as X.
To calculate the hypotenuse, we shall apply the Pythagoras theorem which is,
X² = 3² + 8²
X² = 9 + 64
X² = 73
Adding the square root sign to both sides of the equation, we now have
X = √73
X = 8.5 (approximately)
Now that we have the hypotenuse as 8.5, the Sine of the angle can now be calculated as
Sin0 = opposite/hypotenuse
Sin0 = 8/8.5
