I assume you mean:
3x^2 -5xy + 5y^2.
Simply substitute the given values into the equation:
3(-6)^2 - 5(-6)(2) + 5(2)^2
=188
Answer:
The answer should be 25.
Step-by-step explanation:
Since we can rule out 25.4 for being too high, and 22 for being too low, the answer must be 25
Answer:
72°
Step-by-step explanation:
Given that the radius(r) of the circle is 10 units and the length of arc ABC is 16π
The length of arc ABC = 
Where θ is the central angle in degrees.
Since the length of arc ABC is 16π,

The angle in a circle = 360°, therefore:
Central angle for arc AB (θ) = 360 - Central angle for arc ABC = 360 - 288 = 72°
Therefore the arc measure of arc AB is 72°
Answer:
6x^2 + 3x - 7
Step-by-step explanation:
