Someone please helppp.

Use the distributive property (of which the FOIL method is a special case):

(a - b) (a² + ab + b²)

= (a - b) a² + (a - b) ab + (a - b) b²

= (a³ - a²b) + (a²b - ab²) + (ab² - b³)

= a³ - b³

Alternatively, you can distribute the quadratic expression over each term in a - b :

(a - b) (a² + ab + b²)

= a (a² + ab + b²) - b (a² + ab + b²)

= (a³ + a²b + ab²) - (a²b + ab² + b³)

= a³ - b³

Answer:

The answer is option A y = −1.988x + 43.293

Step-by-step explanation:

I just took the test

The equation of the least squares regression line for the data set will be;

y = -1.988x + 43.293

Option A is true.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The table of data set is shown in figure.

Now, Let hours represent by x.

And, Tickets sold represent by y.

So, By the equation;

y = -1.988x + 43.293

Substitute x = 11;

y = -1.988 × 11 + 43.293

y = - 21.868 + 43.293

y = 21.62

y = 22

And, For x = 9;

y = -1.988 × 9 + 43.293

y = -17.892 + 43.293

y = 25.4

y = 24

Thus, Equation y = -1.988x + 43.293 shows the least-squares regression line for the data set.

So, The equation of the least squares regression line for the data set will be;

y = -1.988x + 43.293

Answer:

10 percent

Step-by-step explanation:

Since the increase is 2 dollars, you divide 20 by 2 to see the percent increase. This equals ten percent.

Hope this helps! Happy friday:)

Answer:

Percent Increase = 10%

Step-by-step explanation:

$22-$20

= $2

Use percentage formula (percentage = increase in price *100 / Initial price)

2*100 / 20

= 200/20

= 10

Answer:

24 units squared

Step-by-step explanation:

you have to first find the area of the base, which is 4 * 4 which is 16. then, to find the area of the triangles, you multiply the base by height, 4 * 3 = 12, and since we have 4 triangles, and one triangle would be (1/2) * base * height, you can multiply this result by 2, which would equal 24

Answer:

[tex]a^{-n}[/tex] is [tex](\frac{1}{a})^{n}[/tex] OR [tex]\frac{1}{a^{n} }[/tex]

[tex]a^{0}[/tex] = 1, where a ≠ 0

Step-by-step explanation:

To simplify the exponents, you must put it in positive value

Example:

The simplest form of [tex]2^{-3}[/tex] is to change the exponent from negative value to positive value.

That means if you want to simplify [tex]a^{-n}[/tex], reciprocal a and change the sign of the power from -n to n

The simplest form of [tex]a^{-n}[/tex] is [tex](\frac{1}{a})^{n}[/tex] OR [tex]\frac{1}{a^{n} }[/tex]

For any number, a (a ≠ 0), 1 × a = a, so, the reason that any number to the zero power is 1 because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, (1)

Example:

The value of [tex](5)^{0}[/tex] = 1, because it is the product of no numbers, so it is equal to the multiplicative identity (1)

That means [tex]a^{0}[/tex] = 1, where a ≠ 0

Very important note:

[tex](0)^{0}[/tex] is undefined value

To me, it looks like it should already be eligible for SAS.

Step-by-step explanation:

SAS stands for Side, Angle, Side (what items have to be congruent for this method to work.)

As we look at the picture,  there are two sides equal, and an angle between them.

So, it looks like SAS is already viable to use, without having to add more information! (at least from what I can say.)

Following the BODMAS rule:

The BODMAS rule follows the order of the BODMAS acronym, in which B – Brackets, O – Order of powers or roots, D – Division, M – Multiplication A – Addition, and S – Subtraction.

The BODMAS rule states that mathematical expressions with more than one operation need to be solved from left to right inside the order of BODMAS.

Hence,
