what is 20-10x10-50 I am typing this bc i have to reach 20 characters lol

Answer:

[tex]\huge\boxed{\sf (10x+9)^2}[/tex]

Step-by-step explanation:

[tex]\sf 100x^2 + 180x+81\\\\= (10x)^2 + 2(10x)(9)+ (9)^2\\\\Using \ Formula \ a^2 +2ab+b^2 = (a+b)^2\\\\= (10x+9)^2\\\\\rule[225]{225}{2}[/tex]

Hope this helped!

Answer:

[tex](10x + 9 {)}^{2} [/tex]

Step-by-step explanation:

1) Rewrite it in the form a² + 2ab + b², where a = 10x and b = 9.

[tex](10x) ^{2} + 2(10x)(9) + {9}^{2} [/tex]

2) Use square sum: ( a + b )² = a² + 2ab + b².

[tex](10x + 9 {)}^{2} [/tex]

Hence, the answer is (10x + 9)².

Answer:

a = 4

Step-by-step explanation:

a² = 5² - 3²

a² = 25 - 9 = 16

√16 = 4

a = 4

Answer:

a = 4

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

a² + 3² = 5²

a² + 9 = 25 ( subtract 9 from both sides )

a² = 16 ( take the square root of both sides )

a = [tex]\sqrt{16}[/tex] = 4

Answer:

Ava's altitude is 3 meters.

Step-by-step explanation:

The position of Ava and Mary can be described by the sides of a right angled triangle. Let Ava's altitude be represented by x.

So that applying the Pythagoras theorem, we have;

[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]

[tex]5^{2}[/tex] = [tex]4^{2}[/tex] + [tex]x^{2}[/tex]

25 = 16 + [tex]x^{2}[/tex]

[tex]x^{2}[/tex] = 25 - 16

   = 9

x = [tex]\sqrt{9}[/tex]

   = 3

x = 3 meters

Thus, Ava's altitude is 3 meters.

Step-by-step explanation:

If 1/2 cup of flour makes a batch of cookies, to make 7 batches you would need 3 and a half cups of flour :D

Answer:

2000mm:80mm:40mm

because 1 m is 1000mm and 1 cm is 10 mm so 2m will be 2000 mm and 8cm will be 80 mm

The simplified ratio will be equal to 10 : 40: 2.

In mathematics, a ratio is a comparison between two quantities or numbers. It is expressed as the quotient or fraction of one number divided by another.

To simplify the ratio of 2m: 8cm: 40mm, we need to convert all the measurements to the same units. One meter is equal to 100 centimeters, so we can convert meters to centimeters by multiplying by 100. One centimeter is equal to 10 millimeters, so we can convert centimeters to millimeters by multiplying by 10.

2m: 8cm: 40mm

= 200cm : 8cm : 40mm (2m = 200cm)

= 200cm : 800mm : 40mm (8cm = 80mm)

= 10 : 40 : 2 (divide all terms by 40 to simplify)

Therefore, the simplified ratio is 10 : 40: 2.

Answer:

1.) 138

2.) 55

Step-by-step explanation:

1.) 8 x 6 = 48 x 2 = 96

   (middle) 8 x 3 = 24

   (triangles) 6 x 3 = 18 divided by 2 = 9 x 2 = 18

96 + 24 + 18 = 138

2.) (middle) 5 x 5 = 25

    (triangles) 5 x 3 = 15 divided by 2 = 7.5 x 4 = 30

     30 + 25 = 55

19.87 = 100%

If you divide both sides by ten, you would get what ten percent is.

1.987 = 10%

Multiply this by two to get 20%.

3.974 = 20%

Minus twenty percent from the original amount.

18.87 minus 3.974 = 15.886 after the discount.

∠3 = 125°

∠6 = 125°

∠7 = 125°

∠8 = 55°

Step-by-step explanation:

This is the detective case for vertical angles!!(dun-dun-dun!!!!)

Ok the info we have is that Angle 2 is 125°

Ok, quick,  take ten seconds, the other group might take the victory coin. What is the vertical angle for angle 2?

-----

3! Correct

3 is the vertical angle because it is one part of the pair of opposite angles made by two intersecting lines.

3 is now 125°

The sum of all angles 1,2,3,4 is 360°

360° - 125° - 125° = 110°

110° / 2 (because 1 and 4 are vertical, they are equal) = 55°

1 = 55° and 4 = 55°

Lets do this for 5,6,7, and 8

Angle 1 = angle 5 because it is the law of same side interior(corresponding) angles, or they are the same because the lines are parallel to each other.

So angle 5= 55°

then angle 8 = 55°

6 = 125° and 7 = 125°

Yay you beat the other team. Great job you win a victory coin(which basically is something that is absolutely nothing)

Step-by-step explanation:

Answer: The answer would be B

Write out the equation in slope-intercept form:

y=-5/3x+6 (Once we know that, it'll be easier to convert it into standard form.)

Subtract -5/3 from both sides of the equation:

y+5/3x=6

Subtract 6 from both sides:

y+5/3x-6=0

Multiply both sides by 3 to get rid of the fraction:

3y+5x-18=0

Then arrange the numbers to x and y are on one side by itself:

3y+5x=18

And that's your answer!

Answer:Matti has 3pencils

Step-by-step explanation:

Given that Jorge has 5pencils

Renaldo has 1more than Jorge that means ,he has 5 +1=6pencils

But also

Renaldo =3Chang-Lin

6==3Chang-Lin

Chang-Lin = 6/3 =2

Since Chang-Lin has 2, Matti having 1more I than Chang-Lin will have 2+1=3pemcils

Answer:

6.45 cm by 1.8 cm

Step-by-step explanation:

Ratio of label to actual measurement ; 2 : 3

For a flyer label size of 4.3

Actual label size equals :

(Flyer ratio / total ratio) * total size = flyer size

2/5 * x = 4.3

2x / 5 = 4.3

2x = 21.5

x = 21.5 / 2

x = 10.75

Actual size =. 10.75 - 4.3 = 6.45 cm

2/5 * x = 1.2

2x / 5 = 1.2

2x = 6

x = 6 / 2

x = 3

Actual size = 3 - 1.2 = 1.8 cm

6.45 cm by 1.8 cm
