If you are good at geometry pls help

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
