Answer: (7+1/7) *(7+7)
Step-by-step explanation:
The correct answer for the given mathematical question above would be option A. The statement that shows two polynomials 4x + 6 and 2x^2-8x demonstrating the closure property when multiplied is that, 8x^3-20x^2-48x is a polynomial. The answer is option A for the given reason: <span>(4x+6)(2x^2 -8x)= 8x^3 -20x^2 -48x</span>
For this case we have the following expression:

Multiplying we have:

We round the expression and we have that it is equivalent to: 20.
Thus,
is approximately equal to 20.
Answer:
The expression given is approximately equal to 20.
