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 /3 = 12/3
x^2 = 4
Take the square root of each side
sqrt(x^2) = ±sqrt(4)
x = ±2
1 cup = 1/4 quart
28 / 4 = 7
7 quarts.
Answer:
theta = 0 theta = 180
Step-by-step explanation:
sin theta = 0
sin ^-1 (sin theta) =sin^-1( 0)
theta = 0 theta = 180 for the limits of theta between 0 and 360
Answer:
