Determine whether 70a3b3+49b5z+b4y2−60xz5+81y370z3 is a monomial, binomial, trinomial, or other polynomial.

is a polynomial equation.

Polynomial is an expression of more than two algebraic terms. Polynomial terms are separated by either a + or - sign.

Monomials, binomials, and trinomials refer to specific types of polynomials that consist of a certain amount of terms (expressions separated by addition and subtraction signs).

Monomials are just one term.

Binomials are two terms

Trinomials are three terms.

As given equation has more than three terms separated by '+' and '-' sign it's known as polynomial.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
