how does (4x + 5)(3x + 10) demonstrate the closure property for polynomials?

Answers

Answer:

Step-by-step explanation:

A polynomial is a finite sum of terms in which all variables have whole number exponents and no variable appears in a denominator.

box4aa

box1

rembox22

The leading term in a polynomial is the term of highest degree.

The constant term in a polynomial is the term without a variable.

Polynomials: YES or NO

3x½

NO - exponent is not a whole number

polyd

NO - the variable is in the denominator

-3x2

YES - satisfies the polynomial definition

polyd1

NO - the square root of x can be written with a fractional exponent of x.

2x-3

NO - exponent is not a whole number.

Negative exponent places x3 in denominator.

polyrad3

YES - the exponent of x is 1 which is OK.

The coefficient being radical 3 is not a problem.

 

Classification by Terms

monomial

one term: 12, 4x, x2, -5xy

binomial

two terms: 2x - 1, x2 - 4

trinomial

three terms: x2 + 2x + 1

polynomial - one or more terms: polynomial means "many", but it can also be one term.

The ending of these words "nomial"

is Greek for "part".

Classification by Degree

Linear - degree of 1 or 0:    3x + 1  or  12

Quadratic - degree of 2:   2x2 - x + 7

Cubic - degree of 3:   3x3 + 4x2 + 3x + 5

definition The degree of a term with whole number exponents is the sum of the exponents of the variables, if there are variables. Non-zero constants have degree 0, and the term zero has no degree.  Example: 6x2 has a degree of 2;   4x2y3 has a degree of 5 (the sum of 2 and 3).

definition

The degree of a polynomial is the highest degree of its terms.

Example: 3x2 + 4x + 1 has a degree of 2;  x3 - x2 + 5x - 2 has a degree of 3

The standard form of a polynomial is when all like terms are combined and the degrees are arranged in descending order.

Polynomial: 2x + 3x5 + 4x3 - 8

Standard form: 3x5 + 4x3 + 2x - 8

3x5 + 4x3 + 2x1 - 8x0

boxdegree1

Will we ever really use the degree?

Knowing the "degree" of a polynomial function will let you determine the most number of solutions the function may have, and the most number of times the function will cross the x-axis.

FYI: The standard form of a polynomial is formally written as anxn + an - 1xn - 1 + ... + a2x2 + a1x + a0, where n is a non-negative integer, and a0, a1, a2, ..., an are real number constant coefficients with an ≠ 0.

bullet Polynomials and Closure:

Polynomials form a system similar to the system of integers, in that polynomials are closed under the operations of addition, subtraction, and multiplication.

CLOSURE: Polynomials will be closed under an operation if the operation produces another polynomial.

• Closure under Addition: (2x2 + 3x + 4) + (x2 - 5x - 3) = 3x2 - 2x + 1

When adding polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the sum has variables and exponents which are already classified as belonging to polynomials. Polynomials are closed under addition.

• Closure under Subtraction: (2x2 + 3x + 4) - (x2 - 5x - 3) = x2 + 8x + 7

When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the difference has variables and exponents which are already classified as belonging to polynomials. Polynomials are closed under subtraction.

• Closure under Multiplication: (x + 1)(x2 + 4x + 3) = x3 + 5x2 + 7x + 3

When multiplying polynomials, the variables' exponents are added, according to the rules of exponents. Remember that the exponents in polynomials are whole numbers. The whole numbers are closed under addition, which guarantees that the new exponents will be whole numbers. Consequently, polynomials are closed under multiplication.

What about division?

Polynomials are NOT closed under division. Look at this simple counterexample:

closure1

When dividing variables with exponents, there is the possibility of creating a negative exponent. Negative exponents are not allowed in polynomials.

A three-dimensional figure with two parallel,congruent bases that are polygons.

Answers

Answer:

The answer would be a Prism.

Step-by-step explanation:

I am really sorry if this is wrong! But I think it is right...

The polygon is Prism.

What is Polygon?

Polygons are defined as plane (two-dimensional) and closed shapes that are formed by joining three or more line segments with each other.

"Polygon" consists of Poly meaning "many" and gon meaning "angle". We see many different polygons around us.

Regular vs Irregular Polygons

It is said that as per Euclidean Geometry, a polygon that is equiangular and equilateral is called a regular polygon while a polygon whose sides are not equiangular and equilateral is referred to as an irregular polygon. A regular polygon is always prefixed by the term "regular". Regular polygons are convex i.e., all the interior angles measure less than 180º.

In simple words, a regular polygon has all angles of the same measure at each vertex and all sides of the same length while a polygon that does not have sides of the same length and measurement of angles at each vertex different is referred to as an irregular polygon.

Given:

A three-dimensional figure with two parallel, congruent bases.

According to the polygon

A prism is a polyhedron that has two congruent and parallel faces (called the base and top), with all its remaining faces rectangles. This means that when a right prism is stood on its base, all the walls are vertical rectangles.
