Is this for a project or something no ones gonna do a whole project and design on for you. The answer would be 36 but maybe ask for tips or help and be more specific.
Answer:

Step-by-step explanation:
we know that
The quadratic equation
is a vertical parabola
The axis of symmetry in a vertical parabola is a vertical line
The equation of the axis of symmetry in a vertical parabola is equal to the x-coordinate of the vertex
The x-coordinate of the vertex is equal to the formula

therefore
the equation of the axis of symmetry is equal to 
The answer is 240 simply multiply 12 x 20
Answer:
third option
Step-by-step explanation:
The n th term of a geometric sequence is
= a₁ 
where a₁ is the first term and r the common ratio
← is in this form
with a₁ =
and r = 2
This is the answer to the problem. Hope it helps
