Answer:
x = ±2
Step-by-step explanation:
3x ^2 -4 = 8
Add 4 to each side
3x ^2 -4+4 = 8+4
3x^2 =12
Divide each side by 3
3x^2 =12
3x^2/3 = 12/3
x^2 = 4
Take the square root of each side
sqrt(x^2) = ±sqrt(4)
x = ±2
The answer is 0.03
0.07 divided by 2.08 = 0.03

The Corectttttt Answerrrrr is C
Sure
Original Equation:
[-5x-16=9x+x-1]
Solve:
[-5x-16=10x-1]
Add (16) to both sides of the equation:
[-5x=10x+15]
Subtract (10x) from both sides:
[-15x=15]
Divide (-15) from both sides:
x=-1
