Answer:
What is factoring?
Factoring is finding what to multiply to find an expression. It is like splitting expression into a multiplication of simplified expression.
Why is it useful to try to factor out the GCF first when factoring?
Greatest common factor or GCF of two numbers is the largest number that divides evenly in both numbers, GCF works the same in polynomials, which divide the expression evenly .
Explain the relationship between factoring and multiplying polynomials. Give an example to help explain
Factoring take away the multiplication, to factorize a polynomial it means take apart what is multiplied. the best example is a²+b²+2ab ( multiplied)
factorize :(a+b)(a+b) take apart what is multiplied
Factor x^2-25, 3x^2-12x-15, and x^3+2x^2+3x+6
x²-25 =(x+5)(x-5)
3x²-12x-15 = 3(x²-4x-5) GCF=3
3(x-5)(x+1)
x³+2x²+3x+6 (x+2) common factor
(x+2)(x²+3)
What are the key features needed to graph a polynomial function?
the key features are the vertex, axis of symmetry, x and y intercept
Explain how to find these key features to sketch a rough graph of a polynomial function
parabola : y=ax²+bx+c
ex: 3x²-12x-15
find vertex (h,k)
h=-b/2a =-(-12)/2(3)=2
k=f(h)=f(2)=3(2)²-12(2)-15
k=12-24-15=-27
vertex=(2,-27)
x intercept is when the graph =0 (y=0)
y intercept when x=0 then y= the constant c and where the graph cross the y axis
axis of symmetry is the x of the vertex: is a line about which a parabola is symmetrical and vertical when the axis of symmetric is vertical.
Why would someone want to factor a polynomial? Provide real world examples of different questions we can answer or facts we can determine from factoring a polynomial.
factor a polynomial helps us understand more about equations,factoring helps us rewrite the polynomial into simpler expression.
example from real life:
A homeowner has a back yard and wants to turn it to garden beds so he can plant his vegetables, he wants to fill it with dirt he needs 240 cubic feet to fill it the length is 4 feet than the width , and the height is 4
solve:
length=W+4
height=1/3 w
V=length* width* height
240=(w+4)(w)(4)
351= 4w²+16w
4w²+16w-240=0
take 4 as common factor
4(w²+4w-60)
now factorize:
4(w-6)(w+10)=0

The formula for finding the volume of a rectangular prism is V = Bh. A rectangular prism with dimensions _________ will have a volume of 150 cubic units.
Answer: 10 * 5 * 3
Step-by-step explanation:
We want to find a base and a height that will multiply together to equal 150 [tex]units^{3}[/tex].
One solution is a [tex]B = 50 units^{3}[/tex] and [tex]h = 3 units^{3}[/tex].
Thus we need a length and width of the base that will multiply together to equal 50 [tex]units^{2}[/tex]. One solution is 10 units * 5 units.
Putting this all together, we have a solution of 10 units * 5 units * 3 units, which will have volume of 150 cubic units.

Show the work please
Solve the linear system using substitution. Show your work.
-8x + 3y = -33
y = -5x + 35
Answer:
x = 6 y = 5
Step-by-step explanation:
-8x + 3y = -33
y = -5x +35
-8x + 3(-5x + 35) = -33
-8x - 15x + 105 = -33
-23x + 105 = -33
-23x = -138
x = 6
-8(6) + 3y = -33
-48 + 3y = -33
3y = 15
y = 5

Aimee has 2 sisters in her family. She thinks the probability of a family having 3 children who are all girls is ¼ because there can be 0 girls, 1 girl, 2 girls or 3 girls.
Aimee designs a simulation to test her prediction. She flips a coin 3 times in a row and records the results. She uses heads to represent a girl and tails to represent a boy. After 10 trials of this simulation, Aimee gets the following results.
1 2 3 4 5 6 7 8 9 10
BBB GBB GGG GGB BBG GGB BGG BGB BBG GBB
Does ¼ seem like a reasonable probability of having 3 girls? Use a tree diagram to model and support your thinking.

A-FIVE
B-SEVEN
C-FOURTEEN
D-FORTY-ONE
E-ONE HUNDRED TWENTY-TWO
Answer:
i think 7
Step-by-step explanation:
Option B: SEVEN
The number that goes not belong in the following series is SEVEN
Given :
The numbers in the series is
2 - 5 - 7 - 14 - 41 - 122 - 365 - 1094 - 3281
First number is 2
[tex]2 \cdot 3 -1=5\\[/tex]
Lets multiply the previous term by 3 and subtract 1 to check the other terms
[tex]5 \cdot 3 -1= 14\\14 \cdot 3 -1= 41\\41 \cdot 3 -1= 122\\122 \cdot 3 -1= 365\\365 \cdot 3 -1= 1094\\1094 \cdot 3 -1= 3281\\[/tex]
From the series we can see that 7 does not belong to the series .
So, SEVEN does not belong to the series .

Write an algebraic expression that is the quotient of a variable term and a constant.
:( sorry im so bad at these. brainlyest will go to who awnsers it first c:
9514 1404 393
Answer:
(47xy)/(6√3)
Step-by-step explanation:
A variable term is one that contains one or more variables, possibly with a coefficient. We can use 47xy as our variable term.
A constant is some number, or a representative of a particular number. π and e and Ф are representative of irrational constants. Of course, any number is also a constant. We can use 6√3 as our constant.
A quotient is formed when a first value is divided by a second value.
Here is the quotient of our variable term and our constant:
[tex]\dfrac{47xy}{6\sqrt{3}}[/tex]
You choose between red or yellow wallpaper, and orange, red, green, blue, or purple carpet. Use the fundamental counting principle to find the total number of possible outcomes when you select one color of wallpaper and one color of carpet. *

5
10
12
Answer:
C. 10
Step-by-step explanation:
There are 5 choices of carpet, and 2 choices of wallpaper. This means that there are only 10 possible outcomes.
The total number of possible outcomes when you select one color of wallpaper and one color of carpet is,
⇒ 10
What is Combination?A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Given that;
You choose between red or yellow wallpaper,
And, orange, red, green, blue, or purple carpet.
Since, There are 2 wallpapers.
And, There are 5 carpets.
Hence, The total number of possible outcomes when you select one color of wallpaper and one color of carpet is,
⇒ ²C₁ × ⁵C₁
⇒ 2 × 5
⇒ 10
Thus, The total number of possible outcomes when you select one color of wallpaper and one color of carpet is, 10

An artist mixes paint to make new colors.
She uses 1/3 cup of red paint and 1/3 cup of yellow paint to make a batch of orange paint.
If the artist has 2 cups of red paint available and 3 cups of yellow paint available, how many batches of orange paint can she make?
Enter your answer in the box.
Answer:
6 batches of orange paint can be made.
Step-by-step explanation:
2 cups of red paint can go to 6 cups of 1/3 a batch of red paint, and 3 cups of yellow paint can go to 9 cups of 1/3 a batch of yellow paint.
She then combines 6 cups of 1/3 cups of red paint with 6 cups of 1/3 cups of yellow paint. The reason it is not 9 is that she doesn't have 3 extra 1/3 cups of red paint.
6 batches of orange paint can be made, with 3 extra 1/3 cups of yellow paint.

Marty went shopping for school supplies. He bought a package of pens for $2.25, a package of paper for $3.25, a notebook for $5.75, and a package of folders for $3.75. What was the range of prices for the school supplies that Marty bought?
Answer:
$3.50
Step-by-step explanation:
to find the range you take the highest number and the lowest number and subtract them
so with that, let us do just that-
$5.75, $3.75, $3.25, $2.25
$5.75-$2.25
=$3.5
and since we're dealing with money we must add a '0' to the end of the decimal- $3.50
good luck :)
