Answer:
3<9n=6 or 3-9n≤6
Step-by-step explanation:
if you are writing an equation I would go with the second
They are all larger than 90 degrees, and in a triangle they would all be obtuse angles.
Find the vertex by using the formula -b/2a
To find a and b, we must know that a and b are located at y = ax^2 + bx + c.
We find that b is 4 and a is 1 by looking at the given quadratic function.
The answer is A. -4/2(1) because the question is looking for the correct steps to find the answer.
