None. 5x3 is a pure number, not a length.
What is the additive inverse of the polynomial –9xy2 + 6x2y – 5x3?
15
An expression. It can be factored out slightly too: 2x6 + 5x3 - 7x4 = x3(2x3 - 7x + 5)

no (5x3)
5.3
The answer is 21

-5
103933.5
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
