the possible values of k?
NGiven f(x) = 2x + ax? - 7a²x - 6 a?, determine whether or not x - a and x + a are
factors of f(x). Hence find, in terms of a, the roots of f(x) = 0.

i think it would be 42cm

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

table 3 represents a direct variation function. : )

6mm^3 or .6cm^3

      216

  36     6

  /   \     /

6     6   6

factor trees are nice.
