2x3+8x9−8x−32 x cubed plus 8 x to the 9th power minus 8 x minus 3

6x7+4x5−8x−36 x to the 7th power plus 4 x to the 5th power minus 8 x minus 3

4x5+6x7−8x−34 x to the 5th power plus 6 x to the 7th power minus 8 x minus 3

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

you probably already have the answer but anyways it's b. 15.0
