? Question Write an expression to represent the perimeter of Melissa's garden in terms of x.
Type the correct answer in each box. Use numerals instead of words.

8x +14

Step-by-step explanation:

This is what I put on mine, but I am not sure if it is correct.

The zero is the x-intercept, where the graph touches the x axis. 
So a quadratic function is a parabola that crosses the x-axis zero, one or two times.
the line of symmetry x=-3 is a vertical line and the space on the right of x=-3 until x=4 has to be equal with the space on the left of x=-3 since that is the line of symmetry 
on the left: |-3|+4 =7
on the left: -(3 +7)= -10

the other zero of the quadratic function is -10
