Answer: x = (3 − i√3)/6 and (3 + i√3)/6
Step-by-step explanation:3x² − 3x + 1 = 0
∴ 3x² − 3x = -1
∴ x² − x = -1/3
∴ x² − x + (-1/2)² = (-1/2)² − 1/3
given x² + bx + (b/2)² = (x + b/2)²
∴ (x − 1/2)² = 1/4 − 1/3
∴ (x − 1/2)² = 3/12 − 4/12
∴ (x − 1/2)² = -1/12
∴ x − 1/2 = ±√(-1/12)
This tells us there are no real roots and if you need real number solutions we stop here
∴ x − 1/2 = ±i/(2√3)
∴ x − 1/2 = ±i√(3)/6
∴ x = 1/2 ± i√(3)/6
∴ x = 3/6 ± i√(3)/6
∴ x = (3 − i√3)/6 and (3 + i√3)/6 <= the 2 complex roots
Answer:
The cost of 4 pound of oranges is 500 and equation represents the cost of C4P pounds of orange is 
Step-by-step explanation:
Let the cost of 1 pound oranges be x
Cost of 3 pound oranges = 3x
We are given that Cost of 3 lb oranges = 375
So, 3x=375
So, x =
So, Cost of 1 pound of oranges =
Let y be the cost of 4 pound oranges
Cost of 4 pound of oranges y =
Cost of 4 pound of oranges y = 500
Hence The cost of 4 pound of oranges is 500 and equation represents the cost of C4P pounds of orange is
Answer:
What is the image?
Step-by-step explanation:
Answer:57/100
Step-by-step explanation:
First, convert 3/10 into hundreths to get a denominator equal to the other:
3/10 km = 30/100km
Add the numerators: 27+30=57
Place numerator over common denominator: 57/100
