The result when we subtract 3x^2 + 7x - 4 from 8x^2 - 6x + 2 is 5x^2 - 13x + 6.
Subtracting polynomials is a method of subtracting polynomials by converting the signs to the opposite sign. It is done in two methods - vertically and horizontally.
Using the method in subtracting polynomials horizontally:
Step 1: Arrange the polynomials in their standard form.
Both 3x^2 + 7x - 4 and 8x^2 - 6x + 2 are in their standard form(exponents in decreasing order)
Step 2: Place the polynomial next to each other horizontally.
(8x^2 - 6x + 2) - (3x^2 + 7x - 4)
Step 3: Distribute the negative sign to the second polynomial.
(8x^2 - 6x + 2) - 3x^2 - 7x + 4
Step 4: Combine the like terms and arrange them in decreasing order.
8x^2 - 3x^2 - 6x - 7x + 2 + 4
Step 5: Perform the calculations.
5x^2 - 13x + 6

Fadil sells televisions. He earns a fixed amount for each television and an additional $20 if the buyer gets an extended warranty. If Fadil sells 11 televisions with extended warranties, he earns $770. How much is the fixed amount Fadil earns for each television
Answer:
770.00 divided by 11 = total cost of 70.00 per tv, subtract 20.00 for extended warranty, TVs were 50.00 each.
Answer:
$50
Step-by-step explanation:
Given: The amount earned by Fadil on selling 11 televisions= $770
Therfore, the amount he earned on selling 1 television=
[tex] \frac{770}{11} [/tex]
=$70
Since, he sold televisions with extended warranty and he earns $20
Then, the fixed amount Fadil earns for each television= $70-$20=$50
So, Fadil earns $50 as the fixed amount for each television.
In a right angled triangle, right angle at C, if AB = 32 cms and sin B=5 by 8 find AC
The numerical length of side AC is 20 units
How to determine the length of AC?The given parameters are:
AB = 32 cm
sin(B) = 5/8
The possible triangle is added as an attachment
From the attached triangle, we have the following sine ratio
sin(B) = AC/AB
This gives
5/8 = AC/32
Multiply both sides of the triangle by 32.
So, we have
AC = 32* 5/8
Evaluate the product
AC = 20
Hence, the numerical length of side AC is 20 units

What is diffusion
Explain how blood clots
When was the first world war fought
Answer:
Blood clotting normally occurs when there is damage to a blood vessel. Platelets immediately begin to adhere to the cut edges of the vessel and release chemicals to attract even more platelets. A platelet plug is formed, and the external bleeding stops.The First World War fought in July 28, 1914.Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration.

Answer:
Milk - 3 cups
Eggs - 2
Self-Raising Flour - 4 cups
Caster Sugar - 2/3 cup
Melted Butter - 50g
Step-by-step explanation:
The question asks for the quantity of each ingredient needed to make 24 pancakes. The recipe we are given makes 12 pancakes.
To figure out our proportions, we can divide the number of pancakes we need to make by how many the recipe makes.
24/12 = 2
This tells us that we will need to double the quantity of each ingredient in the recipe to make 24 pancakes.
1.5 · 2 = 3 cups of milk
1 · 2 = 2 eggs
2 · 2 = 4 cups of self-raising flour
1/3 · 2 = 2/3 cup of caster sugar
25 · 2 = 50g of melted butter

Answer:
H(1 , 0.5)
F(3 , 2,5)
G(5 , 0.5)
Step-by-step explanation:
First step is to get the coordinates of the points.
H(2,1)
F(6,5)
G(10,1)
To find the vertices after a dilation, we multiply the coordinates by the scale factor of the dilation. Since the scale factor is 0.5, its the same as dividing by two.
The new points are
H(1 , 0.5)
F(3 , 2,5)
G(5 , 0.5)

Answer:
{-1, -3, -7}
Step-by-step explanation:
Dividing the given polynomial by (x+1) yields a quotient of x^2 +10x +21. That factors as (x+3)(x+7), so the three zeros are ...
x ∈ {-1, -3, -7}
__
The factors of x^2 +10x +21 are found by looking for factors of 21 that have a sum of 10. Those factors are 3 and 7, so the complete factorization of f(x) is ...
f(x) = (x +1)(x +3)(x +7)
The zeros are the values of x that make these factors be zero. In each case, that x-value is the opposite of the constant in the binomial term.

(8 - x)² = x²
=> 8 - x = x or 8 - x = -x (rejected)

C. It cannot be pie
[tex]\pi[/tex]
D. It is not possible to have a irrational number solution.
Answer:
A. It can be expressed as a non repeating, non terminating decimal.
Step-by-step explanation:
Irrational numbers are numbers with a decimal that goes on forever.
The decimal also never repeats, for the entirety that it goes on.
Since the solution is an irrational number, this means that the solution can be expressed as a non-repeating and non-terminating decimal.
So, A is the correct answer.
