Need help on this please I would really appreciate it :)

Answer:

La opción correcta es;

x² - 4·x·y + 4·y²

Step-by-step explanation:

La ecuación dada es (x - 2·y) ²

(x - 2·y) ² = (x - 2·y) × (x - 2·y) = x·x + x × (-2·y) + (-2·y) × x + (-2·Y) × (-2·y)

Lo que da;

(x - 2·y) ² = x² - x × 2·y - 2·y × x + (-2·y) ²

De lo que tenemos;

(x - 2·y) ² = x² - 2·y × x - 2·y × x + 4·y² = x² - 4·y × x + 4·y²

∴ (x - 2·y) ² = x² - 4·y × x + 4·y² = x² - 4·x · y + 4·y²

Y el resultado del cuadrado simplificado es (x -  ·y) ² = x² - 4·y × x + 4·y² = x² - 4 · x · y + 4·y²

La opción correcta es (x - 2·y) ² = x² - 4·x · y + 4·y².

Answer:

the origin

Step-by-step explanation:

A coordinate grid has two perpendicular lines, or axes, labeled like number lines. The horizontal axis is called the x-axis. The vertical axis is called the y-axis. The point where the x-axis and y-axis intersect is called the origin.

Answer:

29 and 31

Step-by-step explanation:

Let

x = the first odd number

x + 2 = the second odd number

seven times the smaller number is 17 more than six times the larger

7*x = 17 + 6(x + 2)

7x = 17 + 6x + 12

Collect like terms

7x - 6x = 29

x = 29

x + 2 = 29 + 2

= 31

Check:

7*x = 17 + 6(x + 2)

7*29 = 17 + 6(29 + 2)

203 = 17 + 6(31)

203 = 17 + 186

203 = 203

Therefore, the two consecutive odd numbers are 29 and 31

Answer: B = [tex]\frac{-c}{a}[/tex] + [tex]\frac{d}{a}[/tex]

Step-by-step explanation:

you need to get B alone so that would be subtracting everything around it

ab = -c + d

then you need to get that a away from it by dividing both sides by A

B = [tex]\frac{-c}{a}[/tex] + [tex]\frac{d}{a}[/tex]

Answer:

n=-8

Step-by-step explanation:

6.4n + 10= 4.4n -6

Subtract 4.4n on both sides

You then have 2n+10=-6

Subtract 10 on both sides You then have 2n=-16

Divide both sides by 2

n= -8

Hoped that helped

Answer:  n= -8

Step-by-step explanation:

Get all the n's on one side, all the regular numbers on the other  

Add or subtract from both sides

6.4n -4.4n +10  =  4.4n -4.4n -6   So 4.4n -4.4n = 0, "cancels' on right

2.0n  +10 -10 = -6 -10     10's cancel on the left.  -6-10 .=-16 on right

2n = -16    (.0 is not needed in 2.0)  Divide both sides by 2

n = -8

whats the question

Answer:

Slope: 3

y = 3x - 4

Step-by-step explanation:

Slope = rise/run = 3/1 = 3

y = mx + b

m = slope = 3

b = y-intercept = -4

y = 3x -4

Answer:

80%

Step-by-step explanation:

There are 4 shaded sections and 1 unshaded section, so five sections in total.

4 sections are shaded, so the fraction would be 4/5.

Dividing 4/5 gets you 0.8, move the decimal point two places over to get the percent (80%).

Answer:

D. 80%

Step-by-step explanation:

Well, the diagram shows 4/5ths knowing this is more than half we can auto matily mark out the first two A. and B. leaving C. 75% and D. 80% and D. is the best choice (sorry go too lazy to explain...)

Answer:

I'm pretty sure it would be 1 acre

Step-by-step explanation:

5/2 which is improper for 2 1/2 and 2/5 are multiplicative inverses so 2/5 of 5/2 is 1

You do 22/7 and put the remainder over 7.

7 times 3 is 21 so the remainder is 1.

The answer is 3 and 1/7. Choice 3.

Answer:

[tex]3\frac{1}{7}[/tex]

Step-by-step explanation:

Break it up by asking questions. First, how many 7's fit as a whole into 22:

What is the remainder:

Using the original denominator and our above math, write the mixed number:

Answer:

1. 7x

2. x+15

3. 18/x

Step-by-step explanation:

Assume the number is x because we don’t know what it is.

1. Product means multiplication so x * 7 equals 7x.

2. More means addition so x+15.

3. This one is easy. 18 divided by x = 18/x

Answer: 242 = 190 + 4t

Step-by-step explanation:

You know that the maximum capacity of the restaurant is 242 people, meaning that at most there can only be that many customers seated at that time. Normally, the equation would be 242 = 10b + 4t, but since you already know the number of booths, your work is cut in half, giving you 242 = 10(19) + 4t. The equation would be this because you have the capacity being equal to the number of tables x the number of people at each table and the number of booths x the number of people seated at each of them.

Answer:

(DOES NOT BELONG) Is Rational

(DOES NOT BELONG)  Is not Irrational

(DOES NOT BELONG) Is not an integer

(DOES NOT BELONG) Not a Whole

(DOES NOT BELONG) Not Natural

Step-by-step explanation:

This is a fraction with a square root.

Fractions:

Are Not Whole (square root cancels this)

Are Rational BUT since this has a square root, it is not.

Are not natural

Are not integers (Whole numbers that ARE NOT fractions)

So basically from what I have learned, square root cancels literally everything.

Answer:

360 × 30

= (360 × 3) × 10

= 1080 × 10

= 10800

Step-by-step explanation:

For the first two blanks, we will have to find a pair of factors of 30 that will make this the easiest to solve. Lets pair up all of the factors of 30.

1, 30

2, 15

3, 10

5, 6

So now we have found all of the factors of 30. We can eliminate 1 and 30, since we will just end up with 360 × 30 in the second line. We could use 2 and 15, but we will end up with _____ × 15 in the second line, which would be more difficult to solve for than the other two options. Now, you should use any one of the final two pairs of factors. I would use 3 and 10, since I find it much easier to multiply something by 3 and 10 than 5 and 6.

Lets put 3 in the first blank and 10 in the second blank. We will end up with:

(360 × 3) × 10

Now 360 × 3 would be 1080. So the second line would be:

1080 × 10

1080 × 10 would equal 10800. So the final line and the final blank would be:

10800

So in order, the lines would be:

= (360 × 3) × 10

= 1080 × 10

= 10800

I hope you find my answer and explanation to be helpful. Happy studying.
