2x-56. This is the answer because since you don't know what the number is it is gonna be x and twice a number would be 2x. The 56 is subtracted from the 2x because decreased means subtraction.

Which polynomial lists the powers in descending order? A. –10 + 4x3 – 4x5 + 2x4 + x7 B. x7 – 4x5 + 2x4 + 4x3 – 10 C. x7 + 4x3 +

The answer for the exercise shown above is the option B, which is: $x^{7} -4 x^{5} +2 x^{4} +4 x^{3}- 10$
The explanation is shown below:
To list the powers of the polynomial given in the problem above in descending order, you must write the terms from the highest degree to the lowest degree. You have that the highest degree is $7
$ and the lowest degree is $0
$ (Because $-10 x^{0} =-10(1)=-10$ . Therefore, you have that the correct option is the option B.
