Which equation represents a situation in which z varies jointly as x and y?

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

if i put something wrong your not gonna like it so rather not say nothing.
