What is factorization ?To factorize a number, use the factorization formula. Factorization is the process of dividing a whole into components that, when multiplied together, equal the original number. The factorization approach simplifies any algebraic or quadratic equation by using the basic factorization formula, which represents the equations as the product of factors rather than expanding the brackets. Any equation may have an integer, a variable, or the algebraic expression itself as a factor.

Explain how travelling to a ski resort to go skiing could influence travel time
A ski trip requires a lot of planning.You must choose your travel dates, choose the ideal location, identify the best ski resorts for your family in the area, book lodging, purchase lift tickets, schedule lessons, consider your equipment and clothing needs, and possibly book flights or a rental car.
Describe the possible effects that traveling to a ski resort might have on travel time?
Beyond making reservations, there are more actions to be taken.Making decisions, locating the best offers, and making reservations take time.While some tasks should be completed in advance, others can wait till later.Before heading to the slopes, use this helpful planning timeline to help you save some green (and your sanity). Planning is more necessary when skiing with children as it differs from skiing alone.When there was an incredible snowstorm, I remember those last-minute college ski excursions that somehow came together, allowing me to jump in an SUV with someone else and crash on their lily pad with them and 10 to 20 other pals.I have happy recollections of those ski holidays when I was a younger frog. Perhaps I have forgotten the sleepless nights spent in the company of snorers and surviving on sugar and coffee, but those things were unavoidableBut now, on our mountainous excursions, Leap, my husband, who is learning to ski, and two tadpoles are also hopping along.The majority of our preferred ski resorts involve travel by plane, which is difficult to arrange at the last minute due to our tight schedules.In addition, it appears that my standards and working hours have changed, and now I no longer consider sleeping on a couch or the floor with complete strangers to be a vacation. As a result, I must think carefully and plan ahead for my ski trips in order to accommodate a family with a toddler, a tween, and adults.You should begin planning your ski vacation up to a year in advance.Choose the ski region or areas you want to go to.For instance, focus on a specific area; perhaps you want to look into the Denver region, Lake Tahoe, or Utah.Find the finest ski resort for your family by researching ski resorts in those areas.Check out mountain statistics and trail maps to determine if there are any runs that your family will enjoy.In comparison to other resorts, you might notice that one has more terrain for beginner to intermediate skiers. When there aren't any lift tickets or lessons available, it might be difficult to compare pricing during the off-season. To illustrate, imagine that you decide to go skiing in Colorado the next winter a year in advance.To help you plan and get an idea of costs so you can budget, look at the prices of different resorts in the area during peak and off-peak seasons on their websites more than a year in advance. You can also compare the costs of different resorts in the area at both peak and off-peak times.You may discover that Keystone and Breckenridge are more affordable while still providing excellent family-friendly amenities than places like Vail and Beaver Creek.To learn more about ski resort refer

The graph shows the linear parent function.Y5-55----Which statement best describes the function?
From the picture, we have the graph of the linear parent function f(x) = x.
We have the following statements as descriptions of the function:
A. The function is negative when x < 0.
From the graph, we see that the function takes negative values for x < 0. This statement is true.
B. The function is negative when x < 0 and also when x > 0.
The first part of this statement is true, but the second is not because that we see that the function takes positives values for x > 0. So this statement is false.
C. The function is never negative.
If we see the graph, the function is negative when x < 0. So this statement is false.
D. The function is negative when x > 0.
Again, seeing the graph we note that the function takes positive values for x > 0. So this statement is false.
So the only statement that it is true, is option A.

a)The smaller break even quantity is 10
b)The quantity that must be sold to maximize the profit= 14.25
c)The maximum profit = $36.13
STEP - BY - STEP EXPLANATION
What to find?
• The smaller break even quantity is
,• The quantity that must be sold to maximize the profit
,• The maximum profit.
Given:
C(x)= 13x + 370
R(x)=70x - 2x²
a) At the break even quantity, the revenue = cost, that is no profit and no loss.
R(x) = C(x)
So that we have;
70x - 2x² = 13x + 370
Re-arrange.
-2x² + 70x - 13x - 370 =0
-2x² +57x - 370 =0
2x² - 57x + 370 = 0
We can now solve the quadratic equation above.
Using the qudaratic formula
[tex]x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}[/tex]a=2 b=-57 c=370
Substitute the values into the formula and evaluate.
[tex]x=\frac{-(-57)\pm\sqrt[]{(-57)^2-4(2)(370)}}{2(2)}[/tex][tex]x=\frac{57\pm17}{4}[/tex][tex]Either\text{ x=}\frac{57+17}{4}=\frac{74}{4}=\frac{37}{2}[/tex]Or
[tex]x=\frac{57-17}{4}=\frac{40}{4}=10[/tex]x = 37/2 or x=10
We take the smaller value.
Hence, x=10
Therefore, the smaller break even quantity is 10.
b)To find the quantity that will maximize the profit, find the profit function.
p(x) = R(x) - C(x)
P(x) = 70x - 2x² - (13x +370)
= 70x - 2x² - 13x - 370
P(x) =-2x² + 57x - 370
Equate to zero
-2x² + 57x - 370 = 0
2x² - 57x + 370 =0
The maximum is at x = -b/2a
b= -57 and a=2
Substitute the values
x= - (-57) /2(2)
x= 57 /4
x= 14.25
c) To find the maximum profit, simply substitute x=14.25 into the profit function and simplify.
That is;
P(x) =-2x² + 57x - 370
P(14.25) =-2(14.25)² + 57(14.25) - 370
= -406.125 + 812.25 - 370
= 36.125
≈ 36.13
Hence, the maximum profit is $36.13

Determine whether the triangles are similar. If so, what are the similarity statement and the postulate or theorem used? (image attached)thank you ! :)
ANSWER
ΔOMN ~ ΔOJK; SAS
EXPLANATION
As we can observe in the diagram, the triangles share angle O and we have information about the sides forming that angle, so the postulate to use, in case they are similar, is SAS.
If two triangles are similar, then the ratio between corresponding sides is constant.
Let's assume that the similar triangles are triangle OMN and triangle OJK. Then, the previous statement is,
[tex]\frac{OM}{OJ}=\frac{MN}{JK}=\frac{ON}{OK}[/tex]Replace the side lengths for the first and last ratios - since we don't know the lengths of sides MN and JK,
[tex]\begin{gathered} \frac{30+10}{30}=\frac{3+1}{3} \\ \\ \frac{40}{30}=\frac{4}{3} \\ \\ \frac{4}{3}=\frac{4}{3} \end{gathered}[/tex]The ratio between corresponding sides is constant, 4/3. Hence, triangles OMN and OJK are similar, by SAS.

Would you please check this answer for me? Use elimnation to solve the system of equations:2x+2y=162x+3y=14My answer: (10, - 2)
Equation
[tex]\begin{gathered} 2x+2y=16 \\ 2x+3y=14 \\ \end{gathered}[/tex]Let's multiply -1 by Eq 1
[tex]\begin{gathered} -2x-2y=-16 \\ 2x+3y=14 \\ 2x-2x+3y-2y=-16+14 \\ y=-2 \end{gathered}[/tex]Now for x
[tex]\begin{gathered} 2x+2y=16 \\ x=\frac{16-2y}{2} \\ x=\frac{16-2\cdot(-2)}{2} \\ x=\frac{16+4}{2} \\ x=\frac{20}{2} \\ x=10 \end{gathered}[/tex]The answer would be (10, -2)
