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

Jenny's company has 15 trucks in two different sizes. There are small trucks with 6 wheels and large trucks with 12 wheels. Her company needs to inspect the 108 wheels of all of the trucks. How many large trucks does the company have?
Answer: 9
Step-by-step explanation:
The company has a total of 3 big trucks.
What is algebraic expression?An algebraic expression is a combination of terms both variables and constants. We can write the examples of algebraic expression as -
2x + 3y + 5
5x + 4y + 1
Given is that Jenny's company has 15 trucks in two different sizes. There are small trucks with 6 wheels and large trucks with 12 wheels. Her company needs to inspect the 108 wheels of all of the trucks
We can write the system of equations as -
s + b = 15
6s + 12b = 108
6(15 - b) + 12b = 108
90 - 6b + 12b = 108
18 = 6b
b = 4
Therefore, the company has a total of 3 big trucks.

Answer: 36.84
(lmk if this isnt right)
Step-by-step explanation:
To find the perimeter of the rectangle:
3+3+3+3+3+3=18
or
3(6)=18
To find the diameter of the circle:
12-(3+3)
12-6=6
You can combine the 2 half circles to make 1 full circle since they both have the same diameter. Use the circumference formula to solve.
C=πd
Substitute
C=3.14(6)
Multiply
C=18.84
Add the perimeter of the rectangle and the circumference of the circle.
18+18.84=36.84

What equation below shows that the cost, c, depends on how many $5 hats, h, someone buys?
c = 5h
c = h + 5
h = 5 + c
h = 5c
Answer: c = 5h
Step-by-step explanation:
C is equal to the total cost, and h is equal to the number of hats bought.
So, as a verbal equation, we have:
total cost = price x number of hats bought
We know the price ($5) and the variables, so we can substitute these:
c = 5h

If 47 Mph was a unit rate, how many hours would it take to travel 1 Mph?
Answer: um i think you asked the question wrong. But ok.
Step-by-step explanation:
= 47 miles per hour
This is a fraction equal to
47 miles ÷ 1 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 1
47 miles ÷ 1
1 hours ÷ 1
=
47 miles
1 hour
=
47 miles
hour
= 47 miles per hour
Answer:
It would take you a total of .021 of an hour to get there.
Step-by-step explanation:
So, you are asking if 47 mph was a unit rate, how long would it take to travel 1 mile? Ok, so you would convert this to a unit rate, which would be 1 hour.47 miles because you are trying to get the 47 to a 1. Next, you will divide both numbers by 47, giving you .0212765957/1. This rounds to .021/1.

Jeff had $20. He spent 3/8 of his money on lunch. How much money does jeff have left?
Answer:
$12.50
Step-by-step explanation:
3/8 x 20/1 = 7.5
20 - 7.5 = 12.50
Jeff has $12.50 left after spending 3/8 of his money on lunch.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Jeff had $20.
Jeff spent 3/8 of his money on lunch.
To find the money he left after spending on lunch we get by subtracting three by eight from one.
1 - 3/8
=8-3/8
= 5/8 of his money left.
To find out how much money Jeff has left, we can multiply the remaining fraction by his initial amount of money:
Intitial amount is 20
The money left is 5/8.
Multiply five by eight with twenty.
Money left = (5/8) × $20
Five divided by eight times of twenty.
=100/8
When hundred is divided by eight we get twelve point five.
= $12.50
Therefore, Jeff has $12.50 left after spending 3/8 of his money on lunch.
