(2x-y)^2

[tex](2x - y)^2[/tex]. This expression represents the result of squaring the difference between 2x and y.

1. **Difference between 2x and y:** The difference between 2x and y is calculated by subtracting y from 2x. This gives us the expression "2x - y," which represents the numerical difference between these two quantities.

2. **Square of the Difference:** To square this difference, we simply multiply "2x - y" by itself. When you square something, you multiply it by itself. In mathematical notation, squaring is denoted using an exponent of 2, which is written as "^2."

So, combining the two steps, we have:

[tex](2x - y)^2[/tex]. This expression represents the result of squaring the difference between 2x and y. When you expand this expression, you get a quadratic expression, which may include terms like [tex]4x^2, y^2[/tex], and -2xy, among others, depending on the values of x and y.

The length of the rectangle is 11.24 inches (approx.)

We have a rectangle whose area is 107.52 in² and its width is equal to 9.6 inches.

We have to determine its length.

The area of a rectangle is -

A(R) = Length x Breadth = L x B

According to the question -

Area of rectangle (A) = 107.52 square inches.

Width of rectangle (B) = 9.6 inches.

We know -

Area of a rectangle = L x B

Therefore -

107.92 = L x 9.6

[tex]$L=\frac{107.92}{9.6}[/tex]

L = 11.24 inches (approx.)

Hence, the length of the rectangle is 11.24 inches (approx.)

Answer: (2,-2) (-1,1) (-3,-1) (-2,-4)

Step-by-step explanation:

The x-axis is the horizontal line and the y-axis is the vertical line on a graph. The ordered pairs are always in (x,y).

To perform a geometry reflection, a line of reflection is needed; the resulting orientation of the two figures are opposite. Corresponding parts of the figures are the same distance from the line of reflection. Ordered pair rules reflect over the x-axis: (x, -y), y-axis: (-x, y), line y=x: (y, x).

For the first inequality, just add 3 to both sides.

For the second inequality, add 4 to both sides then divide both sides by 3.

Answer:

a 90° clockwise rotation about the origin and then a reflection a cross the x-axis

The correct sequence is  90° clockwise rotation about the origin and then a reflection a cross the x-axis.

There are two different directions of rotations, clockwise and counterclockwise: Clockwise Rotations (CW) follow the path of the hands of a clock. These rotations are denoted by negative numbers. Counterclockwise Rotations (CCW) follow the path in the opposite direction of the hands of a clock.

So, according the given transformation the point A' appears on right side then is clockwise rotation.

If it was counterclockwise rotation then point A' appears on left side.

After that is over x- axis then it is reflection across the x-axis.

Answer:

Your math teacher deserves to be fired.

The example for this is 1.23 × 4.5 (none of your questions, I know)

Anyway we want to do this lining up the digits like so:

 1.23

× 4.5

NOT

  1.23

× 4.5

Now we want to multiply all the digits (1, 2, 3) in the top number (1.23) by the 5 in 4.5. We'll start with the 3 in 1.23.

Since 3 × 5 is equal to 15, we will put the ones digit of 15, 5, in that place.

 1.23

× 4.5

     5

Now we need to carry the 1 in the 15 to be used in 2 (of 1.23) multiplied by the 5 (in 4.5). Now we will get 2 × 5 + 1 which equals 11. We carry the 1 in 11 to the next part.

    [tex]_{1}[/tex]

 1.23

× 4.5

    15

So we currently have the digits 15 for our answer. Now we move to the next part where we do 1 × 5 + 1 which is equal to 6. Our problem is now:

  [tex]_{1}[/tex]

 1.23

× 4.5

  615

Now we can move to the next row where we do the exact same thing where we multiply the digits in 1.23 BUT instead of 5, we now multiply them each by 4 since our number is 4.5. However this is different, before starting to multiply, we need to put a 0 in the ones digit of the 2nd row of our answer like so:

  [tex]_{1}[/tex]

 1.23

× 4.5

  615

+      0

Now we can start to multiply.

    [tex]_{1}[/tex]

 1.23

× 4.5

  615

+   20

then

 [tex]_{1}[/tex]  

 1.23

× 4.5

  615

+  920

then

 [tex]_{1}[/tex]  

 1.23

× 4.5

  615

+4920

Now we are almost at our solution, we need to now add our 615 and 4920. That then is equal to 5535. Now since we have 3 digits in total in 1.23 & 4.5 BEHIND the decimal point, we need to put a decimal point 3 digits to the right of 5535 so then it becomes 5.535. Hopefully, this helps? I didn't answer them immediately because if you never learn how to do long multiplication (what this is called) then you'll likely fail at all other math. Trust me, I know, I've done that before, I hope you don't make the same mistake because the feeling when everyone else is ahead of you and you're still at the basics is horrible.

Anyway answers for your question because I think I'll likely be reported for not answering your question:

Answer:

x=8 or (8,0)

Step-by-step explanation:

The x-intercept of a function is the value of which y=0, or the coordinate points where the function crosses through the x-axis.

Observing the attached graph, you can see that the line crosses the x-axis at the point (8,0). This means that x=8 when y=0, which holds true algebraically since x+4y=8 -> 8+4(0)=8 -> 8+0=8 -> 8=8.

Therefore, the x-intercept of the function is x=8 or (8,0).

Step-by-step explanation:

The easiest way to find the answer is to convert all of the fractions to have the same denominator,...

A = (22/55 / 11 = 2/5 and 2/5 * 20)            = 40/100

B = (17/20 * 5)                                             = 85/100

C = (4/5 * 20)                                              = 80/100

D = (3/4 * 25)                                              = 75/100

B (Lily) is the highest followed by C (Nikki), D (Sydney), and A (Monica)
