Quad. 4.
x is positive & y is negative.
Answer:
3xy.
Step-by-step explanation:
HCF of 6 and 9 = 3.
HCF of x and x^2 = x.
HCF of y^3 and y = y.
So that would be 3xy.
Answer: -1 ± <em>i</em>√35

Step-by-step explanation:
From the quadratic equation,
X = -b ±√b² - 4ac
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
2a
From the given equation, -3x² - x - 3 = 0
where a = -3, b = -1, c = -3
Now substitute for the values in the formula above
x = -(-1) ± √(-1)² - 4(-3)(-3)
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
2(-3)
x = 1 ± √ 1 - 36
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
-6
x = 1 ± √ -35
⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
-6
x = -1 ± <em>i√35 this is because it has a negative root.</em>

<em> The answer is b</em>
The formula to find the area of a sector is:
A = 
In this case:
Degree = 40
Radius = 8
^^^Plug these numbers into the formula given above
A = 
Solve
A = 
π8²
A = π64
A = 
A = 7.1111111π
When rounded:
7.1π is the area of the sector
Hope this helped!
