Faelyn noticed that she does not have a common factor. Which accurately describes what Faelyn should do next?
Faelyn should realize that her work shows that the polynomial is prime.
Faelyn should go back and regroup the terms in Step 1 as (6x4 + 3x2) – (8x2 + 4).
In Step 2, Faelyn should factor only 2x out of the first expression.
Faelyn should factor out a negative from one of the groups so the binomials will be the same.
Answers
Answer:
(b) Faelyn should go back and regroup the terms in Step 1 as (6x⁴ + 3x²) – (8x² + 4)
Step-by-step explanation:
You want to know the next step in factoring 6x⁴ -5x² -4 after noticing the terms have no common factor.
TrinomialFaelyn can notice the variable terms are powers of x², meaning this expression is a quadratic in x². As such, it may be able to be factored using the same strategies available for factoring quadratic expressions.
One such strategy is to rewrite the middle term as a sum, then group the terms and factor each group. Faelyn has apparently noticed that she can rewrite -5x² as 3x² -8x². This means ...
Faelyn should go back and regroup the terms in Step 1 as (6x⁴ + 3x²) – (8x² + 4), choice B.
__
Additional comment
The values used to rewrite the x² term are factors of (6)(-4) = -24 that have a sum of -5. Those values are +3 and -8.
Once Faelyn has regrouped the terms, she can factor further as ...
(6x⁴ + 3x²) – (8x² + 4) = 3x²(2x² +1) -4(2x² +1) = (3x² -4)(2x² +1)
These two binomial factors are prime.

Answers
we know that
MN=16 in-------------> PQ=MN
PQ=16 in
L is the midpoint of PQ-----------> distance QL=PQ/2
QL=8 in
if m∠QLM = 45°
then

MQ=8 in
Perimeter=[MN]*2+[MQ]*2=16*2+8*2=48 in

The recipe makes enough stew for 6 people, and the ingredients cost $9.75. How much would it cost to serve 24 people? Use the rate table to solve the proportion.
Answers
Answer: The required cost of ingredients that would serve the recipe to 24 people is $39.
Step-by-step explanation: Given that a recipe makes enough stew for 6 people and the ingredients cost $9.75.
We are to find the cost of the ingredients that would make recipe to serve 24 people.
We are to use the rate table to solve the given problem.
Since the rate of increase of number of people is given by
[tex]\dfrac{24}{6}=4.[/tex]
Therefore, we will multiply the cost of ingredients for 6 people by 4.
Therefore, the cost of ingredient that makes the recipe to serve 24 people will be
[tex]=9.75\times 4\\\\=39.[/tex]
Thus, the required cost of ingredients that would serve the recipe to 24 people is $39.

The area of a sector of a circle is given by the equation A=3.14r^2S/360, where r us the radius of the circle and S is the angle measure of the sector. If Mia solved this equation for S, which of the following equations did she write?
Answers
to solve for s we proceed as follows:
multiply both sides by 360, this will give us:
360A=3.14r²S
next we divide both sides by 3.14r²
360A/(3.14r²)=(3.14r²S)/(3.14r²)
This will give us:
S=360A/(3.14r²)
Just took the quiz.
The answer is 360A / pi r^2

The graph shows the distance in miles of a runner over x hours. What is the average rate of speed over the interval [9, 11]?
A. 2/5
B. 1
C.2
D.5/2
Answers
Therefore, we can find the average rate of change as follows:
m = (y2-y1) / (x2-x1)
m = (11-6) / (11-9)
m = (5) / (2)
m = 5/2
Answer:
the average rate of speed over the interval [9, 11] is:
D. 5 / 2
Answer:
Hence, option D is correct.
(i.e. Average speed is 5/2 miles/hour)
Step-by-step explanation:
We are asked to find the average rate of speed over the interval [9, 11].
We know that average speed is given as the ratio of total distance over total time.
the distance when time=9 hours is 6 miles.
and the distance when time=11 hours is 11 miles.
Hence, average speed is given as:
[tex]Average speed=\dfrac{Total distance}{Total time}\\\\Average speed=\dfrac{11-6}{11-9}\\\\Average speed=\dfrac{5}{2}[/tex]
Hence average speed is 5/2 miles/hour.
A charity organization had a fundraiser where each ticket was sold for a fixed price of $ 70. They had to sell a few tickets just to cover necessary production costs. After selling 10 tickets, they were still at a net loss of $800, (due to the production costs). Let (n)P, denote the net profit from the fundraiser P (measured in dollars) as a function of the number of tickets sold n. Write the function's formula.
Answers
12000+1200=13200,

it asks net profit, so you need to minus $1200 to find it.
Answer: The function's formula would be
[tex]P(n)=Revenue-Cost\\\\P(n)=70n-1500[/tex]
Step-by-step explanation:
Since we have given that
Price of each ticket = $70
Number of tickets = 10
Total cost price of tickets would be
[tex]70\times 10\\\\=\$700[/tex]
After selling 10 tickets, there is a net loss of $800.
So, Total product cost would be
[tex]\$700+\$800\\\\=\$1500[/tex]
We need to write the function's formula for the number of tickets sold 'n'.
So, the function's formula would be
[tex]P(n)=Revenue-Cost\\\\P(n)=70n-1500[/tex]

You work for a furniture moving company. Your boss sends you to the hardware store to buy tie down rope. He tells you to buy the best deal. What is the best deal on rope?
A) 10 feet for $7.00
B) 20 feet for $13.00
C) 50 feet for $28.00
D) 100 feet for $57.50
Answers
Answer:
Option C- 50 feet for $28.00 is the best deal because it offers rope $0.56 per feet.
Step-by-step explanation:
To know what is the best deal on rope, we calculate the price for 1 feet rope from the given deals.
A) 10 feet for $7.00
1 feet = 7.00 ÷ 10 = $0.70
B) 20 feet for $13.00
1 feet = 13.00 ÷ 20 = $0.65
C) 50 feet for $28.00
1 feet = 28 ÷ 50 = $0.56
D) 100 feet for $57.50
1 feet = 57.50 ÷ 100 = $0.575
Option C) 50 feet for $28.00 offers lowest price, so this is the best deal.
Answer:
The best deal is "50 feet for $28.00"
C is correct
Step-by-step explanation:
We need to buy tie down rope for moving furniture.
We have to choose best deal from four option.
We are given length of rope and price of rope.
We can identity best deal if we know the price of rope per feet.
So, first we change each option into per feet.
Option A) 10 feet for $7.00
Price of 10 feet rope = $7
Price of 1 feet rope = $0.70
Option B) 20 feet for $13.00
Price of 20 feet rope = $13.00
Price of 1 feet rope = $0.65
Option C) 50 feet for $28.00
Price of 50 feet rope = $28.00
Price of 1 feet rope = $0.56
Option D) 100 feet for $57.50
Price of 100 feet rope = $57.50
Price of 1 feet rope = $0.5750
Now, we arrange each per feet price and check best deal.
0.70 > 0.65 > 0.57 > 0.56
The minimum cost is $0.56
Hence, The best deal is "50 feet for $28.00"

What is the simplified form of the expression? 3/a-9b
Answers
Final answer:
The simplified form of 3/(a-9b) is 3/a - 1/3b.
Explanation:
The closest relevant excerpt appears to be “(a + b)/h, āb/h + (a + b)(a + b)/h = (a + b)/h” which simplifies to “(a + b)/h”, assuming the intention was to demonstrate simplification through common denominator aggregation or algebraic manipulation. The mostly likely possible simplification in this can be done in the following form.
The simplified form of the expression 3/(a-9b) is 3/a - 1/3b.
To simplify, we split the fraction into two: 3/a - 3/(3b) = 3/a - 1/3b.

what is the equation of the line that has a slope of 4/5 and a y-intercept of -1?
Answers
Answer:
y = 4/5x -1
Step-by-step explanation:
The slope-intercept form of the equation of a line is ...
... y = mx + b . . . . . . for slope m and y-intercept b
You have m = 4/5 and b = -1. The equation of the line is found by putting these values in their places in the form above.
... y = 4/5x -1
The equation of the line with a slope of 4/5 and a y-intercept of -1 is y = (4/5)x - 1.
The equation of a line in slope-intercept form is given by y = mx + b, where m represents the slope of the line and b represents the y-intercept.
Given a slope of 4/5 and a y-intercept of -1, we can substitute these values directly into the slope-intercept form equation to get the equation of the line.
Hence, the equation for this line is y = (4/5)x - 1.
