Well, we know standard form of quadratic equation : ax² + bx + c where,

a = Coefficient of x²

b = Coefficient of x

c = Constant term

We also equation for determinant :

⇒ b² - 4ac

Here, if value of determinant i.e. (b² - 4ac) = A perfect Square, then we can understand that the givdn equation is factorisable.

But, if the value of (b² - 4ac) ≠ A perfect square, then it will be considered as "Not factorisable"

Now let's calculate whether the equation is factorisable or not :

Comparing the given equation with ax² + bx + c, we get :

a = 1

b = -3

c = -54

Putting values in the determinant equation :

⇒ (-3)² - 4(1 × -54)

⇒ 9 + 216

⇒ 225

⇒ 15²

So, determinant = A perfect square

That means the given equation is factorisable.

Now let's factorize with by middle term splitting :

⇒ x² - 3x - 54

⇒ x² -(9 - 6)x - 54

⇒ x² - 9x + 6x - 54

⇒ x(x - 9) + 6(x - 9)

⇒ (x + 6)(x - 9) [Required Solution]

Hence, we get our required solution.

Answer:

y = -x + 7

Step-by-step explanation:

y = x + 4   slope: 1

slope of perpendicular line: -1

for (2,5)   y interception (b) = y - mx = 5 - (-1)*2 = 7

equation: y = -x + 7

check: -x+7 = -2+7 =5

Answer:

a) [tex]1\,cm^{2}[/tex] is [tex]\frac{1}{6}[/tex] of area A.

b) [tex]1\,cm^{2}[/tex] is [tex]\frac{1}{18}[/tex] of area B.

c) [tex]1\,cm^{2}[/tex] of [tex]\frac{1}{3}[/tex] of area C.

d) [tex]1\,cm^{2}[/tex] of [tex]\frac{1}{4}[/tex] of area D.

e) [tex]1\,cm^{2}[/tex] of [tex]\frac{1}{2}[/tex] of area E.

Step-by-step explanation:

According to stament, the area A is 6 square centimeters, the area B is 18 square centimeters, the area C is 3 square centimeters, the area D is 4 square centimeters and the area E is 2 square centimeters.

The purpose of this exercise is determine all ratios associated with each area, defined as a given area divided by the total area. Then, we proceed to determine each result:

([tex]A_{given} = 1\,cm^{2}[/tex], [tex]A_{A} = 6\,cm^{2}[/tex], [tex]A_{B} = 18\,cm^{2}[/tex], [tex]A_{C} = 3\,cm^{2}[/tex], [tex]A_{D} = 4\,cm^{2}[/tex], [tex]A_{E} = 2\,cm^{2}[/tex])

[tex]r_{A} = \frac{1\,cm^{2}}{6\,cm^{2}}[/tex]

[tex]r_{A} = \frac{1}{6}[/tex]

[tex]r_{B} = \frac{1\,cm^{2}}{18\,cm^{2}}[/tex]

[tex]r_{B} = \frac{1}{18}[/tex]

[tex]r_{C} = \frac{1\,cm^{2}}{3\,cm^{2}}[/tex]

[tex]r_{C} = \frac{1}{3}[/tex]

[tex]r_{D} = \frac{1\,cm^{2}}{4\,cm^{2}}[/tex]

[tex]r_{D} = \frac{1}{4}[/tex]

[tex]r_{E} = \frac{1\,cm^{2}}{2\,cm^{2}}[/tex]

[tex]r_{E} = \frac{1}{2}[/tex]

a) [tex]1\,cm^{2}[/tex] is [tex]\frac{1}{6}[/tex] of area A.

b) [tex]1\,cm^{2}[/tex] is [tex]\frac{1}{18}[/tex] of area B.

c) [tex]1\,cm^{2}[/tex] of [tex]\frac{1}{3}[/tex] of area C.

d) [tex]1\,cm^{2}[/tex] of [tex]\frac{1}{4}[/tex] of area D.

e) [tex]1\,cm^{2}[/tex] of [tex]\frac{1}{2}[/tex] of area E.

Answer:

24

Step-by-step explanation:

Using ratios, we know that PQ/PT = PR/PS = QR/TS

of course, we know this because of AA similarity.

PQ/PT = 1/2

so PR/PS = 1/2 => PS = 12*2 = 24

Answer:

24

Step-by-step explanation:

PQ is half of PT, therefore, if PR = 12, PS = 24

Answer:

25% increase

Step-by-step explanation:

length is 24 inches after the increase and width is 33 inches (i did length as up and down and width as side to side, that's how I always do it but I might be wrong let me know and I can fix it)

the area before it gets increased it 600

after the increase its 792

and 600 is 75.75% of 792

so it would be 25.25% increase

sorry this was so long hope this helps

Answer:

range is 17

Step-by-step explanation:

Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is 93−76=17 93 - 76 = 17 .

Answer: 100 candy bars

Step-by-step explanation:

You did not include the question but judging by the progression I can assume that the question is along the lines of how many candy bars they will need to sell to reach their target.

You did not include the amount they have to raise as well so let us assume that number is $375.

Assuming they have to raise $375 and they have already raised $125, the amount left to be raised is:

= 375 - 125

= $250

With each candy bar selling at $2.50, the number of candy bars they will need to sell is:

= 250/ 2.50

= 100 candy bars

You should use this process to find the answer to your question.

Step-by-step explanation:

Romantic writers have the advantage of writing what they feel not just what they made up. Romantic writers can make a book sad, scary, and happy. Whereas fictional books almost always end up perfect for the main character. I do think that the techniques and styles were effective for the themes and subjects being addressed because they flow into the subject. Using an absolute sob story for a romantic book could be passed off as a hit if you use the right techniques. So, yes. I do think that the techniques and styles were effective for the themes and subjects being addressed.
