Think a moment about factoring a polynomial by finding the GCF.
Explain the role of the GCF in factoring a polynomial.
Where is the GCF placed after factoring the GCF?
How do you verify factoring is correct?
Answer/Step-by-step explanation:
Explain the role of the GCF in factoring a polynomial.
The role of the GCF in factoring a polynomial is the largest monomial that divides evenly into each term. GCF is a factor that is shared by all terms within a polynomial. For instance, if we have a polynomial of the form A*B + A*C, the GCF is A since both terms have A as a factor.
Where is the GCF placed after factoring the GCF?
After factoring out the GCF, it's placed outside the parentheses, in front of the rest of the polynomial. Like the sample we previous use A*B+A*C = A(B+C).
How do you verify factoring is correct?
To Verify factoring is correct distributing the GCF to the polynomial within the parentheses.

Maria is training for a triathlon. Yesterday, she rode her bike for eight and two-thirds miles in two-thirds of an hour. If Maria continues to rides at the same rate, how far will she ride in one hour?
HELP
Answer:
She will ride 13 miles in one hour
Step-by-step explanation:
(8 2/3) / (2/3) = x / 1....8 2/3 miles to 2/3 hr = x miles to 1 hr
cross multiply
(2/3)(x) = (8 2/3)(1)
2/3x = 26/3
x = 26/3 * 3/2
x = 26/2...which equals 13....she will ride 13 miles in 1 hr

First of all, the G.C.F. stands for
Greatest Common Factor
So we need to find the Greatest Common Factor of the polynomials.
And yea, polynomials have Greatest Common Factors as well.
So, let's find all the Greatest Common Factors. :)
First, we have
[tex]\bold{28x^2yz}[/tex] and [tex]\bold{16xy^2}[/tex]
What are the common factors of these polynomials?
Well, there are plenty of them, like 2, 2x, y...
What is the Greatest Common factor?
Is it Option A, 12xy?
No, because neither 28 nor 16 is divisible by 12.
So we cross out Option A.
Is it Option B, 8xy?
No, because 28 isn't divisible by 8, and remember, if a number is evenly divisible by another number, then that number is a factor.
Example: 8 is a factor of 16 (16÷8=2); 8 is not a factor of 28, because
28÷8=3.5 (a decimal, not a whole number)
Is it Option C, 4xy?
Yeah, it seems like Option C is the right option.
[tex]\huge\checkmark[/tex]Both 28 and 16 are divisible by 4
[tex]\huge\checkmark[/tex]Both polynomials have an x and a y in them
[tex]\rule{250}{2}[/tex]
Find the GCF:
[tex]\bold{5x^2y^4,\:10x^3y^5, \:and\:15xy^2}[/tex]
Once again, is it Option A, 5x^3y^5?
No, because
✘ 5 and 10 aren't divisible by 3
✘ None of the 3 polynomials has a 3y term
In other words, Option A is wrong.
How about Option B?
You should see right off the bat that 5 and 15 aren't divisible by 10.
So now we have 2 options left.
Is it Option C, 5xy²?
Well,
✓All 3 polynomials are divisible by 5
✓ All 3 polynomials have a y² term
✓ All 3 polynomials have an x term.
Hence, the answers are
[tex]\boxed{\boxed{\bold{1. \;Option\;C; 2.\;Option\;C.}}}[/tex]
Hope everything is clear.
If you have any questions, please comment.

Helen has a new beaded necklace. 80% of the 75 beads on Helen's necklace are blue. How many blue beads are there on Helen's necklace?
Answer:
80% of 75 = 60
Step-by-step explanation:
first make 80% a decimal so 0.8 because 80/100 = 0.8
the multiply 0.8 by 75
this will give you 60
Therefore Helen's necklace has 60 blue beads

Calculate the volume of this prism
Answer:
800 cm³
Step-by-step explanation:
The volume is the product of the base area and the "height" of the prism. Here, the base can be considered to be a 10 cm × 12 cm rectangle with a 4 cm × 5 cm cutout. Its area will be ...
A = (10 cm)(12 cm) -(4 cm)(5 cm) = 120 cm² -20 cm² = 100 cm²
The product of this base area and the 8 cm height of the prism is ...
V = Bh = (100 cm²)(8 cm) = 800 cm³
The volume of the prism is 800 cm³.

Interpreting direct variation from a graph
The graph of the direct variation passes through the origin
The revolution per foot of travel is 0.2The slope of the graph is 5The revolution per foot of travelFrom the graph, we have the following points
(x.y) = (0,0) and (2,10)
Where:
x represents the number of revolutions
y represents the distance in feet
The revolution per foot of travel (r) is then calculated as:
[tex]r = \frac{x_2 -x_1}{y_2 -y_1}[/tex]
This gives
[tex]r = \frac{2 - 0}{10 - 0}[/tex]
[tex]r = 0.2[/tex]
This means that, the revolution per foot of travel is 0.2
The slope of the graphThis is the reciprocal of the revolution per foot of travel
In (a), we have:
[tex]r = 0.2[/tex]
So, the slope is:
[tex]Slope = \frac 1{0.2}[/tex]
[tex]Slope = 5[/tex]

Question -
If the ratio of the sums of first n^th terms of two AP's is (7n + 1):(4n + 27) find the ratio of their m^th terms.
[tex]\rule{200}4[/tex]
Answer : The required ratio is (14m-6):(8m+23) .
[tex]\rule{200}4[/tex]
Here we are given that the ratio of sum of first n terms of two AP's is (7n + 1):(4n + 27) .
That is.
[tex]\small\sf\longrightarrow \dfrac{S_1}{S_2}=\dfrac{7n +1}{4n +27} \\[/tex]
As , we know that the sum of n terms of an AP is given by ,
[tex]\small\sf\longrightarrow \pink{ S_n =\dfrac{n}{2}[2a +(n-1)d]} \\[/tex]
Assume that ,
First term of 1st AP = a First term of 2nd AP = a'Common difference of 1st AP = dCommon difference of 2nd AP = d'Using this we have ,
[tex]\small\sf\longrightarrow \dfrac{S_1}{S_2}=\dfrac{\dfrac{n}{2}[2a + (n-1)d]}{\dfrac{n}{2}[2a' +(n-1)d'] } \\[/tex]
[tex]\small\sf\longrightarrow \dfrac{7n+1}{4n+27}=\dfrac{2a + (n -1)d}{2a' + (n -1)d' } . . . . . (i) \\[/tex]
Now also we know that the nth term of an AP is given by ,
[tex]\longrightarrow\sf\small \pink{ T_n = a + (n-1)d}\\[/tex]
Therefore,
[tex]\longrightarrow\sf\small \dfrac{T_{m_1}}{T_{m_2}}= \dfrac{ a + (n-1)d }{a'+(n-1)d'}. . . . . (ii)\\[/tex]
[tex]\longrightarrow\sf\small \dfrac{T_1}{T_2}=\dfrac{2a + (2n-2)d}{2a'+(2n-2)d'} . . . . . (iii)\\[/tex]
From equation (i) and (iii) ,
[tex]\longrightarrow\sf\small n-1 = 2m-2\\[/tex]
[tex]\longrightarrow\sf\small n = 2m -2+1 \\[/tex]
[tex]\longrightarrow\sf\small n = 2m -1 \\[/tex]
Substitute this value in equation (i) ,
[tex]\longrightarrow \sf\small \dfrac{2a+ (2m-1-1)d}{2a' +(2m-1-1)d'}=\dfrac{7(2m-1)+1}{4(2m-1) +27}\\[/tex]
Simplify,
[tex]\longrightarrow\sf\small \dfrac{ 2a + (2m-2)d}{2a' +(2m-2)d'}=\dfrac{14m-7+1}{8m-4+27}\\[/tex]
[tex]\longrightarrow\sf\small \dfrac{2[a + (m-1)d]}{2[a' + (m-1)d']}=\dfrac{ 14m-6}{8m+23}\\[/tex]
