Answer:
[tex]x^{4}[/tex] + 3x³ - 3x - 1
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = lw ( l is the length and w the width ) , thus
A = (3x² - 2x - 1)(x² + x + 1)
Each term in the second factor is multiplied by each term in the first factor, then
A = 3x²(x² + x + 1) - 2x(x² + x + 1) - 1(x² + x + 1) ← distribute parenthesis
= 3[tex]x^{4}[/tex] + 3x³ + 3x² - 2[tex]x^{4}[/tex] - 2x² - 2x - x² - x - 1 ← collect like terms
= [tex]x^{4}[/tex] + 3x³ - 3x - 1

The tides change as the three interact.
Step-by-step explanation:
When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides—both commonly called spring tides.

Drink a soda the instant you feel one coming on- sugar and caffeine tend to help.
If you can, try a good chiropractor- they can do adjustments that help with so many things including splitting headaches.
Try an OTC medicine.
sleep, dark, quiet, calm- try not to think too much and stay hydrated. maybe try carbonated water.
try to massage your neck yourself. it could help.
try to use a cold or a hot compress on your head.
Bananas. A tried and true natural headache reliever, bananas have potassium, magnesium, B vitamins, and complex carbohydrates, all components that contribute to headache relief.
The taste and smell of green apples have shown to help dim or lessen the intensity of migraines.
Hot packs and heating pads can relax tense muscles. Warm showers or baths may have a similar effect. Drink a caffeinated beverage. In small amounts, caffeine alone can relieve migraine pain in the early stages or enhance the pain-reducing effects of acetaminophen (Tylenol, others) and aspirin.

Find the equation of the line
Use exact numbers
y=___x+____
y = -1.5x + 3 is the equation of the line
How to find the equation of the line?
The general form of the equation of a line is y = mx + b,
where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).
slope (m) = (y2-y1)/(x2-x1)
From the graph: x1 = 0, y1 =3 and x2 = 2, y2 = 0
m = (0-3)/(2-0) = -3/2 = -1.5
From the graph: b = 3
Therefore, the equation of the line is y = -1.5x + 3

If you answer it and show the work for me then I will give you the brainiest question reward!
Please Help!
Answer:
(7 , 5)
Step-by-step explanation:
Add all the x-axis then divide by 3
7 + 3 + 11 = 21
21/3 = 7
Add all the y-axis then divide by 3
9 + 3 + 3 = 15
15/3 = 5
So answer will be (7,5)
The coordinates of the centroid of triangle ABC.
(x, y)
Where,
x = Sum all the x-coordinates of the vertices ÷ 3
y = Sum o
The coordinates of the centroid is (7, 5).
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
The vertices of the triangle in the diagram below are:
A(7,9), B(3,3), and C(11,3).
Now,
The coordinates of the centroid of triangle ABC.
(x, y)
Where,
x = Sum all the x-coordinates of the vertices ÷ 3
y = Sum of the y-coordinates of the vertices ÷ 3
Now,
x = 7 + 3 + 11 / 3 = 21/3 = 7
y = 9 + 3 + 3 / 3 = 15/3 = 5
Now,
The coordinates of the centroid is (7, 5).

Estimate the value of y when x =2.5
Both of them
Step-by-step explanation:
[tex]y = {2.5}^{2} - 2(2.5) - 3 [/tex]
-1.75
Here we need to learn how to read a graph.
In a normal graph we have the inputs (the values of x) in the horizontal axis and the outputs in the vertical axis.
Here we want to see what is the value of y for the blue graph when x = 2.5
We will find y = -1.5
(the blue graph is the one that corresponds to: y = x^2 - 2x - 3)
To find this:
The first thing we need to do is find x = 2.5 in the horizontal axis.
Now that we found it, we need to draw a vertical line, and see at which point of the blue graph this vertical line intersects the curve. At that point we draw an horizontal line that intercepts the vertical axis.
At that point we have the y-value
You can see an example of this, a good estimation by only looking at the graph is y = -1.5
For the other point, the value of x when y = 1.
We do exactly the same thing but in the inverse order, we first find y = 1
Then we draw an horizontal line that intercepts the graph
Then we draw a vertical line that intercepts the x-axis and we find the value.
We can see that for y = 1 we have x = 3.2 aprox.
