Which of the following polynomials is in standard form (Picture)

D

Step-by-step explanation:

A polynomial in standard form has the terms in ascending order.

In other words, the term with the largest degree is on the left, followed by the term with the second largest degree, etc.

The largest term in this polynomial is 2x³. Thus, we need to start with that.

The only choice that starts with 2x³ is choice D.

Thus, choice D is in standard form.

And examining choice D, we see that it is in ascending order all the way through.

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
