What are polynomials?A polynomial is a mathematical equation made up of coefficients and indeterminate that can only be solved using the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables.
A polynomial exists as an expression consisting of indeterminate and coefficients, that concern only the processes of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.
Vertical addition exists as s procedure of adding where the numbers are lined up in columns according to their place values. Likewise, vertical subtraction exists as a method of subtracting where the numerals exist lined up in columns according to their place values.

The author's message is that a person cannot predict the future without first learning about the past. The author does this by providing an example of how one wants to read without knowing the letters of the alphabet. Obviously, you can't read without first learning the letters of the alphabet. With the reading example, the author is explaining that just like a person trying to read without learning the alphabet first, a person predicting the future without knowing their history first is doing the exact same thing, it's nearly impossible.
What is the quotient of 2.592\times 10^72.592×10 7 and 7.2 \times 10^47.2×10 4 expressed in scientific notation?
The quotient, expressed in scientific notation, is:
Quotient = 0.36 × 10³
Given:
(2.592 × 10⁷) / (7.2 × 10⁴)
To find the quotient of 2.592 × 10⁷ and 7.2 × 10⁴ and express it in scientific notation, we divide the coefficients and subtract the exponents.
Quotient = (2.592 × 10⁷) / (7.2 × 10⁴)
Dividing the coefficients, we get:
Quotient = 2.592 / 7.2 = 0.36
Subtracting the exponents, we get:
10⁷ - 10⁴ = 10⁽⁷⁻³⁾ = 10³
In scientific notation, the coefficient should be between 1 and 10, so we can rewrite the expression as:
Quotient = 0.36 × 10³

Mr. Trainer is building a bookcase. He has two wooden boards that are each 8 feet long. He needs to cut the wooden boards into pieces that are 16 inches long. What is the greatest number of 16-inch pieces that Mr. Trainer can cut from the two wooden boards? (1 foot = 12 inches)
Answer:
12
Step-by-step explanation:
Length of one of the boards = 8 feet
Converting to inches
[tex]1\ \text{foot}=12\ \text{inches}\\\Rightarrow 8\ \text{feet}=8\times 12=96\ \text{inches}[/tex]
One cut is 16 inches
So, we divide the length of the board by 16
[tex]\dfrac{96}{16}=6[/tex]
So, one board is cut into 6 pieces.
The other board is also 8 feet long.
So, the number of pieces the other board is cut into is also 6.
Hence, a total of [tex]6+6=12[/tex] pieces of each 16 inches long can be cut from the two boards.
which two are equivalent expressions?
Answer:
4t and t+t+t+t

Stephen purchased a guitar, which was originally priced at $80 but
discounted at 25%. He also had to pay 5% sales tax. What amount did
Stephen pay to purchase the guitar? *
Answer:
57 dollars
Step-by-step explanation:
1. Solving the 25% discount
25% = .25
80 x .25 = $20
80 - 20 = $60
** We subtracted 80 from 20 because 25% of 80 is 20 BUT We're taking 25% OFF of 80 because it was a discount.
2. Solving the 5% Tax
5% = .05
$60 x .05 = 3
$60 + 3 = $63
**Adding tax to the discounted price

A candy store sells 7 packs of bubble gum for $29.33. How much would it cost to buy 3 packs?
Hi there,
Recall how 7 packs for gum sell for $29.33.
Before we can calculate how much it would cost to sell 3 packs of gum, we must calculate how much it would first cost to sell 1 pack of gum.
The cost of 1 pack of gum is the current total cost divided by the total amount of gum packs you receive at that price.
In this case, the total cost is $29.33, and we receive 7 gum packs at that price.
Therefore, the cost of 1 pack of gum is [tex]\frac{29.33}{7}[/tex], which equates to $4.19.
We now know that each pack of gum costs $4.19.
Hence, 3 packs of gum would cost three times that price.
[tex]4.19 * 3 = 12.57[/tex]
The cost of 3 packs of gum is $12.57.
Hope that helps!
Answer:
$12.57
