∆ABC is reflected about the line y = -x to give ∆A'B'C' with vertices A'(-1, 1), B'(-2, -1), C(-1, 0). What are the vertices of ∆ABC?

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

da freeck kinda math is this just drop out

step-by-step explanation:

so, converting firstly the mixed fractions to improper fractions and then "adding".
