Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients. The formula when solved for h will be equal to A/4b.
What is a polynomial?Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication, and non-negative exponentiation of variables involved.
A.)
For the given octagon, if its diagonals are made then it will be divided into 8 triangles, such that each triangle will be equal to the other.
Now, if the area of a single triangle is calculated then the area of the triangle will be,
Area of triangle = (1/2) × b × h
Further, since there are 8 triangles, therefore, the area of the octagon can be written as,
Area of octagon = Area of triangle × 8
= (1/2) × b × h × 8
= 4bh
Hence, the area of the octagon is 4bh.
B.)
The formula can be solved for h as shown below,
Area of octagon = 4bh
A = 4bh
Divide both the sides by 4b, therefore, we can write,
A/4b = 4bh/4h
h = A/4b
Hence, the formula when solved for h will be equal to A/4b.

Encuentren dos números cuyo cociente sea -1 y que la resta del primero menos el segundo sea -3/2
Answers
Answer:
[tex]\dfrac{3}{4}\ \text{and}\ \dfrac{-3}{4}[/tex]
Step-by-step explanation:
Find two numbers whose quotient is -1 and the subtraction of the first minus the second is -3/2
Let two numbers are x and y. When they are divided the quotient is -1. So,
[tex]\dfrac{x}{y}=-1[/tex]
It can also be written as :
x = -y ....(1)
The subtraction of first minus the second is -3/2 .
[tex]x-y=\dfrac{-3}{2}\ .....(2)[/tex]
Use equation (1) in (2),
[tex]-y-y=\dfrac{-3}{2}\\\\-2y=\dfrac{-3}{2}\\\\y=\dfrac{3}{4}[/tex]
From equation (1) : [tex]x=\dfrac{-3}{4}[/tex]
Hence, two numbers are [tex]\dfrac{3}{4}\ \text{and}\ \dfrac{-3}{4}[/tex].

An expression is given: 2 open parentheses square root of k minus 1 close parenthesis plus square root of 8. If on adding negative 6 square root of 2to the expression results in a rational number, what is the value of k?
Answers
Answer:
Possible value of k is √2
Step-by-step explanation:
The information given are;
The expression, 2·(√k - 1) + √8 to which may be added -6·√2 to obtain a rational number, we therefore have;
2·(√k - 1) + √8 - 6·√2 = R
Therefore, simplifying gives;
2·√k - 2 + 2·√2 - 6·√2 = 2·√k - 2 - 4·√2 = R
2·√k - 2 - 4·√2 + 2= R + 2 = R
2·√k - 2+ 2 - 4·√2 = R
2·√k - 2+ 2 - 4·√2 = R
2·√k + 0 - 4·√2 = 2·√k - 4·√2 = 2·(√k - 2·√2) = R
(√k - 2·√2) = R/2 = R
Therefore, √2 is a factor of √k such that √k - 2·√2 = R
Which gives k = x·√2, where x = a rational number
When x = 1, k = √2.
Therefore, a possible value of k is √2

When Natalie finishes drawing the large triangle on the poster board, what will be the approximate measure of side BC? Round to the nearest centimeter.
Answers
Answer:
31 cm
Step-by-step explanation:
The complete question is attached.
A triangle is a polygon with three sides (three edges and three vertices). There are different types of triangles which are equilateral triangles, right triangles, scalene triangles, obtuse triangles, acute triangles, and isosceles triangles.
An equilateral triangle is a triangle in which all its sides are equal and all its angles are equal to 60°.
From the triangle, AB = BC = AC = 9.5 cm
Since the triangle is enlarged 3.25 times, hence:
new length of BC = 9.25 cm × 3.25 = 30.875
New length of BC = 31 cm to nearest cm

proper order of the four towns.
Answers
Answer:
W, M, A and G
Step-by-step explanation:
The question is not correct, the correct question is Adams, Greensburg, Middletown, and Waldron are four towns in Indiana on a nearly straight highway. If the highway is represented by a line, the towns can be represented by four points: A, G, M, and W. Given that MG + WM = WG and MA = MG - AG determine the proper order of the four towns.
Answer: The line segment addition postulate states that for a line segment AC with point B which lines on AC, then this equation holds:
AB + BC = BC
Given that MG + WM = WG, this means that point M lies between the segment WG.
Also, MA = MG - AG
MA + AG = MG, hence point A lies between segment MG
Therefore the order of the points is W, M, A and G

Write the equation for g(x)
Please answer I need help ASAP
Answers
==================================================
Explanation:
We're given that f(x) = x^2
The function g(x) is vertically stretched to be five times taller. We see this with the point (1,5) on the purple graph since its counterpart is at (1,1) on the blue graph.
We look at how the y values changed. So we had gone from y = 1 to y = 5. This jump means "multiply by 5"
If we do this to all the y values on the blue graph, then all the points jump to a height 5 times taller. Something like (2,4) moves to (2,20). Something like (3,9) goes to (3,45). And so on. This is what produces the purple g(x) graph.
You could say that
g(x) = 5*f(x)
g(x) = 5x^2
This works because y = f(x), so when we say 5*f(x), we really mean 5*y.

Jenna bought 5 reams of paper at the store for a total of $21. The tax on her purchase was $1. Solve 5x + 1 = 21 to determine the price for each ream of paper.
Answers
Answer:
$4
Step-by-step explanation:
From the question we have it that jenna bought the 5 reams of paper at a price of 21
The tax on this was $1
The total cost of the paper minus tax = $20
Cost of 1 team = total cost of paper / quantity
= 20/5
From the equation
5x +1 = 21
5x = 21 -1
5x = 20
X = 20/5
X = $4
Therefore we have The cost of a team of paper to be equal to $4
