How I can apply the distribute property to this question?

14 = 2•7 and 35 = 5•7, so the GCF of 14k and 35 is 7.

14k + 35 = 2•7k + 5•7 = 7 (2k + 5)

(Remember that the distributive property says a (b + c) = ab + ac.)

it's

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
