Mrs. snell is writing a book. she has already written 25 pages and
decides to write 4 pages a day to reach a total of 225 pages.
which equation can be used to
determine how many days d mrs. snell needs to write to reach
225 pages?

4d+25=225

I am not sure what are the options, if this is one, here is your answer, if it isn't an answer...could you please post them?

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
