Step-by-step explanation:

This should be your expressions: [tex]\displaystyle{x^2+2x-24}[/tex], this can be factored by applying in the form of:

[tex]\displaystyle{x^2+(\alpha + \beta)x+\alpha \beta = (x+\alpha)(x+\beta)}[/tex]

This simply means you have to find two numbers that add up or subtract and obtain the middle term, and that two numbers must also satisfy the last terms as well. (Hence, two numbers adding up to middle term and multiply to last term.)

We can check by seeing into the factor of 24 which are:

These numbers have product of 24. Next, we find the middle term -- since the middle term is positive value. This means that the highest value is in positive.

From factors that we list, we can cancel off the followings:

Therefore, the only factors left are 4 and 6. These two also make 2 (6-4), so we will have [tex]\alpha[/tex] = 6 and [tex]\beta[/tex] = -4. Therefore:

[tex]\displaystyle{x^2+(6-4)x+6(-4) = (x+6)(x+(-4))}\\\\\displaystyle{x^2+2x-24= (x+6)(x-4)}[/tex]

And there you have it, the factor of x² + 2x - 24

Step-by-step explanation:

If and only if a function is a bijective function, it has an inverse that is also a function.

Only in the condition, if a function is bijective, meaning it is both onto (surjective) and one-to-one (injective), it has an inverse that is itself a function. If there are no two random input values resulting in a similar output value, then the function is said to be injective. As a result, there is only one x-value that can yield a given y-value.

A unique inverse function cannot be determined for a function if it is not injective. Whereas, a function is surjective if at least one input value is required to produce each output value. As a result, there is at least a single x-value in the domain of the function that yields each y-value in the function's range. A function's inverse would not be defined for values in the range if it were not surjective.

The conjecture regarding a number and it's absolute value being always opposites is incorrect.

The counterexample is that the absolute value of any positive number is always the own number.

The absolute value of a number is the number without the signal, representing the difference between the number and zero.

For example:

|-2| = |2| = 0.

Hence the conjecture is false, as the absolute value of any positive number is always the own number.

The conjecture would be true if it stated this only for negative numbers, then the absolute value of a negative number is in fact always the opposite of the number.

The solutions of the quadratic equation 3x^2 + 14x + 5 = 0 can be found by factoring the equation into the product of two binomials, which are equal to zero.

3x^2 + 14x + 5 = (3x+1)(x+5) = 0

To find the solutions, we set each factor equal to zero and solve for x:

3x+1 = 0 or x+5 = 0

x = -1/3 or x = -5

Therefore, the solutions of the quadratic equation 3x^2 + 14x + 5 = 0 are x = -1/3, x = -5.

Alternatively, you can use the Quadratic formula to find the solutions.

The Quadratic formula is: x = (-b ± √(b^2-4ac))/(2a)

Where a,b and c are the coefficients of the equation.

x = (-14 ± √(14^2-435))/(2*3) = (-14 ± √(196-60))/6 = (-14 ± √(136))/6

It's worth noting that both solutions x = -1/3 and x = -5 are correct.

The dividend is influenced by both the quotient and the divisor when the remainder is zero.

Any integer that divides a different number is the divisor. A factor, on the other hand, is a divisor that completely divides a number and leaves no remainder. Therefore, all factors are also divisors of a number. But not every divisor will also be a factor. The factors of 20 in the aforementioned case are 4 and 5.

We are left with a value after division if a number (dividend) cannot be divided entirely by another number (divisor). The term "remainder" refers to this amount.

Step-by-step explanation:

Megan has to pay 29.10 dollars for the sweater after 20 % decrease in cost and a tax of 7 %.

After the discount and the tax is applied, Megan will pay 29.10 dollars for the sweater.

Here we have to determine that how much did Megan pay in total

We know that originally, the sweater costs $ 34.00, and there is a 20 % decrease in that cost and a tax of 7 %.

The decrease of 20 % is written as a factor:

[tex]$1- \frac{20}{100}[/tex] = (1 - 0.2)

The decrease of 20 % is (1 - 0.2).

And an increase of 7 % is written as a factor:

[tex]$1+\frac{7}{100}[/tex] = (1 + 0.07)

The increase of 7 % is (1 + 0.07).

Then the amount that Megan pays for the sweater is:

P = 34.00 × (1 - 0.2) × (1+0.07)

P = 34.00 × (0.8) × (1.07)

P = 29.10

Shapes that are identical to each other are considered congruent. There are no differences in the matching sides or angles.

What is a congruent shape?

Congruent refers to things that are exactly the same size and shape. Even if we flip, turn, or rotate the forms, the shape and size should remain the same.

Congruent refers to something that is "absolutely equal" in terms of size and shape. The shapes hold true regardless of how we rotate, flip, or turn them.

Shapes that are identical to one another are said to be congruent. Both the matching sides and the corresponding angles match. We must examine all of the shapes' angles and sides in order to accomplish this. Two shapes that are similar to one another can be stacked perfectly.

Step-by-step explanation:

[tex]\sf{Travel\: time = \dfrac{Distance}{Speed}}[/tex]

The time taken to travel the first 600 km

[tex]= \dfrac{600}{90} = \dfrac{20}{3}\; \sf{hours}[/tex]

This leaves 200 km which was travelled at a speed of 100 km/hr

Time taken for this stretch = 200/100 = 2 hours

If the entire trip were driven at 90 km/h, it would take the same time as the first case. Therefore we only need to be concerned about the last 200km

If the last 200km were traveled at 90 km/h instead of 100 km/h, time taken

[tex]=\dfrac{200}{90} = \dfrac{20}{9}\\\\[/tex]

The difference in time then would be:
[tex]=\dfrac{20}{9} - 2\\\\\\= \dfrac{20}{9} - \dfrac{18}{9}\\\\=\dfrac{2}{9}\; hour[/tex]

Step 1: The greatest common factor (GCF) in this equation is x^3. So we can factor it out:

y = x^3(x - 343)

What does a math equation mean?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Step 2: We can not take root of a³ and b as there is no square term in the equation.

Step 3:

a= x^3

b= - 343

Step 4: Plugging in a and b into the original equation, we get

y = x^3(x - 343)

This is the simplified form of the equation.

So, the equation is a polynomial equation of degree 4, with the leading coefficient a = x^3 and the constant term b = -343, and it can be written as y = a(x-b) which is y = x^3(x-343)

A triangle is a three-sided polygon whose sum of all the angles is always 180 degrees, not 90 degrees.

No, a triangle is not 90 degrees. In geometry, a triangle is a three-sided polygon with three angles. The sum of the angles in a triangle is always 180 degrees.

This can be proved using the fact that a straight line is 180 degrees. If we draw a straight line, and divide it into two angles, which are supplementary angles. Therefore, these angles add up to 180 degrees. In a triangle, we can draw one straight line and divide it into three angles, which are supplementary angles, therefore the sum of the angles in a triangle is always 180 degrees.

For example, if a triangle has angles of 90 degrees, 60 degrees, and 30 degrees, the sum of these angles is 180 degrees (90+60+30=180).
