y=7 or 7 seven degrees Celsius.
Step-by-step explanation:
Answer: 39.58 cm
Step-by-step explanation:
The circumference of a circle is 2 times the radius times pi or pi times the diameter. so we know the diameter is 12.6 so just multiply it by pie.
12.6 * pi = 39.584
Now rounded to the nearest hundredth is 39.58.

Answer:
see explanation
Step-by-step explanation:
Given a quadratic equation in standard form, ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant Δ = b² - 4ac informs us about the nature of the roots.
• If b² - 4ac > 0 then 2 real and distinct roots ( solutions )
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then roots are not real
Given
3x² - 6 = 2x ( subtract 2x from both sides )
3x² - 2x - 6 = 0 ← in standard form
with a = 3, b = - 2, c = - 6 , thus
b² - 4ac = (- 2)² - ( 4 × 3 × - 6) = 4 - (- 72) = 4 + 72 = 76
Since b² - 4ac > 0 then the solution is 2 real and distinct roots
