Answer:
<u>The correct answer is C. 9 -√ 105/ 2, 9 + √ 105/ 2</u>
Step-by-step explanation:
Let's find the solutions for the quadratic equation:
x² = 9x + 6
x² - 9x -6 = 0
Using the quadratic formula, we have:
x = [- (-9) +/- √ (-9)² - 4 * 1 * -6]/2 * 1
x = [ 9 +/- √ (81 + 24]/2
x = [ 9 +/- √ (105]/2
x₁ = [ 9 + √ (105]/2
x₂ = [ 9 - √ (105]/2
<u>The correct answer is C. 9 -√ 105/ 2, 9 + √ 105/ 2</u>

Answer:
V=12
Step-by-step explanation:
Faces: 20 Edges: 30
Write the Euler's formula for 3-dimensional figures
F+V=E+2
Substitute some variables for their known values
20+V=30+2
Add the numbers on the right side of the equation
20+v=32
Subtract 20 on both sides
20-20+V=32-20
Subtract
V=32-20
Number of Vertices
V=12
Answer:
- By Double splitting method
=> 2x²-7x+5
=> 2x²-2x-5x+5
=>2x(x-1)-5(x-1)
<h2>=>(2x-5)(x-1)</h2>
