Select one:
a. (2x - 3)(ky - 2mn + nx)
b. (2x - 3y)(k + 2m - n)
c. (2x + 3y)(k - 2m + n)
d. (2x + 3)(ky + 2mn - nx)

Answer 1

Answer 2

Its B right?

Answer 3

I looked at all the choices
and just the last term times the last term:
a) -3 * nx = -3nx there is no -3nx in the original . So (a) is out
b) - 3y * -n= +3ny in the running
c) +3y*n= +3ny in the running
d) +3*-nx= -3nx out

so its b or c

Answer 4

b gives the correct -3yk
c gives +3yk

so b it is.

But I did not multiply it out entirely. If there are typos in the question we might not notice.

Answer 5

ok
