Answer:
54
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>
Answer:
n = -5/2
Step-by-step explanation:
4n - 2 = 6n + 3
-2 = 2n + 3
-5 = 2n
n = -5/2
