The lengths of three sides of a triangle are a 2x + 1/5 feet , 4x + 1/2 feet , and x + 1/5 What is the perimeter of the triangle?

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
