What operations would the set of quadratics be closed under? For each operation, explainwhy it is closed or provide an example showing that it isn’t.Type your response here:x^2-1+(x^2+2x+1)=2x^2+2x closed under addition.(x^2-1)-(x^2+2x+1)=-2x-2 not a quadratic(x^2-1)(x^2+2x+1)=x^4+2x^3-2x-1 no above degree 2(x^2+2x+1)/(x^2-1)=1+(3x+1)/(x^2+2x+1) not a quadratich. Is there a set of expressions that would be closed under all four operations? Explain.Type your response here: Polynomials with a degree of 0, real numbers, andrational numbers.

Answer:
Cost of 1 packet of biscuit=Rs 9
Cost of 1 packet of toffee=Rs 13
Step-by-step explanation:
Let
Cost of 1 packet of biscuit=x
Cost of 1 packet of toffee=y
We have to find the cost of 1 packet of biscuit and 1 packet of toffee.
According to question
Now,
Using the value of y then, we get
Substitute the value of x
Hence, cost of 1 packet of biscuit=Rs 9
Cost of 1 packet of toffee=Rs 13
