At the bottom of each graph is the starting point and you can see the red graph starts at 0 where the other does not
We are asked to solve for the zeros of the given quadratic equation f(x) = 9x2 + 6x + 1. To solve this, first, we need to set the given equation into zero such as the succeeding solution is shown below:
0 = 9x2 + 6x +1
Perform factoring such as:
0 = (3x + 1) (3x + 1)
Solving for x1, we have:
3x + 1=0
3x = -1
x1 = -1/3
Soving for x2, we have:
3x +1=0
x = -1/3
Therefore, the zeroes of the given expression is both -1/3 for x1 and x2.

Answer: 40.56ft.
Step-by-step explanation:
First, lets find the perimeter of the half circle: c = 2pi(r)
pi = 3.14
r = 4
3.14 * 4 = 12.56
12.56 * 2 = 25.12
Then, because it is only have a circle, divide by 2.
25.12/2 = 12.56
10 + 10 + 8 + 12.56 = 40.56
