1x15 3x5 5x3 15x1
All of them. 1x15,2x7.5, 3x5, 4x3.75, 5x3...
None. 5x3 is a pure number, not a length.
factor the 18. 18=2x3x3. Take out the 3 because it is squared. 5x3 radical 2=15radical2

What is the additive inverse of the polynomial β9xy2 + 6x2y β 5x3?
15
An expression. It can be factored out slightly too: 2x6 + 5x3 - 7x4 = x3(2x3 - 7x + 5)
