Step-by-step explanation:
Use the quadratic formula

x=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}
x=2a−b±b2−4ac
Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

The answer is 60
Answer:
Step-by-step explanation:
I'm assuming this is linear and that there is no special on a larger order of wings. To find the unit price of each piece, divide $28.80 by 16 to get that each piece cost $1.80 (that's a lot for a single chicken wing. That better be one BIG chicken...). To find the cost of 9 wings, multiply 9 by $1.80 to get $16.20
