The answer will be .425. Hope it help!
Answer:
The coordinates of the vertex are (-5, 41)
Step-by-step explanation:
For a quadratic function of the form

Where a, b and c are constants and represent the coefficients of the function, then the symmetry of the parabola always passes through its vertex.
In this case we have the following parabola

And we know that its axis of symmetry is the line 
Then we know that this axis of symmetry passes through the vertex of the parabola.
Therefore, the x coordinate of the vertex is -5.
To find the coordinate in y of the vertex, we substitute x = -5 in the function.

Finally, the vertices are in the point (-5, 41).
Answer:
The second one
Step-by-step explanation:
She started with x dollars and then used 8 dollars to buy a football game ticket, so x-8. Then, she is left with 56 dollars, so x-8=56. Therefore, the second story represents the equation.
Might be late but since the area is a squared unit (m^2), it's 2-dimensional perimeter is just a plain unit(m), it's 1-dimensional the 2-dimensional ratio is 112/63 Then, the 1-dimensional ratio is sqrt(112/63), which is 4/3. Plus i just took the quiz and got that question right :)
