Question

evaluate the polynomial 6x-7 for 1/2n2 -1/2n and y =2

Answer 1

Can't, as we don't know how any of those equations are related.

Answer 2

what do u mean

Answer 3

You haven't provided any equation that relates the three variables (x, n, y). By "relate", I mean none of the equations provided contain either of the variables in the same equation. Kind of like asking someone to convert 100 dollars to 100 yen without providing a rule for it.

Answer 4

thats all it says on my paper

Answer 5

Also, 1/2n2=1/4n, assuming "2n2" = 2*n*2, so 1/2n2-1/2n= -1/4n

Answer 6

my answer choices are a.15 or b. -20 or c.4 or d.-16

Answer 7

Have you typed the problem correctly?
