Vertex = -b/2a
Therefore, you must change each of these eachs in the form of a+b+c. Take the coefficient to find the vertex.
1. x^2+6x+11 —> -6/2(1) = -3
2. x^2+8x+34 —> -8/2(1) = -4
3. x^2+4x+7 —> -4/2(1) = -2
The answer is B.208,418cm
Answer:
Step-by-step explanation:
Use the Pythagorean theorem to find the length x of the third side.
x² + 6² = √90²
x² = 90-36 = 54
x = √54 = 3√6
Uhh I think something like y=x+5
