Best ResponseYou've already chosen the best response.1well for A using pythagoras' theorem \[h^2 = (4x 10)^2 + (x 5)^2\] for B the area \[A = \frac{1}{2} \times (x 5)(4x 10)\]

Best ResponseYou've already chosen the best response.1all that is is says is that if you multiply 2 polynomials then you get a polynomial as an answer... if you add 2 polynomials you still get a polynomial. so using pythagoras' theorem squaring each polynomial will result in a degree 2 polynomial then adding the 2 degree 2 polynomials still results in a polynomial so it is a closed operation. the area question, you have degree 0 polynomial, degree 1 polynomial and degree 1 polynomial so multiplying them will result in a polynomial of degree 2 hope it makes sense
