what is the missing term?
1. (x+2)^2 = __ +4x+4
2. (2x-3)^2 = 4x^2+__+9y^2
3. (3x+4)^2 = 9x^2 + 24x+__
4. (x-y)^2= __-2xy+y^2
5. (2x+3y)^2 = 4x^2+__+9y^2

Answers

Answer 1

Answer:

see explanation

Step-by-step explanation:

The general expansion of (a + b)² is

(a + b)² = a² + 2ab + b²

Applying this to the following expansions

(1)

(x + 2)² = x² + 2(2x) + 2² = x² + 4x + 4 ← missing term is x²

(2)

(2x - 3)² = (2x)² + 2(2x)(- 3) + 3² = 4x² - 12x +9 ← missing term is - 12x

(3)

(3x + 4)² = (3x)² + 2(3x)(4) + 4² = 9x² + 24x + 16 ← missing term is 16

(4)

(x - y)² = x² + 2(x)(- y) + y² = x² - 2xy + y² ← missing term is x²

(5)

(2x + 3y)² = (2x)² + 2(2x)(3y) + (3y)² = 4x² + 12xy + 9y² ← missing term is + 12xy

There are 3 points on the plane.Explain or determine whether point C is closer to point A or point B.

Answers

Point C us closer to point B because if you connected the points B would be in the middle of C going to A line.

Step-by-step explanation:

I hope I helped!

The perpendicular line from a point to a line is the shortest distance from the point to the line

With regards to the three points on the plane, point C is closer to point B

The reason point C is closer to point B is as follows:

The known parameter is;

Three points, A, B, and C, are located on a plane

Required:

To explain or determine whether point C is closer to point A or point B

Method:

Define, the relationship between the destination points A, and B

Find the shortest distance from point C, to the definition of points A, and B

Solution:

The relationship between points A, and B is that they form the line segment AB

The shortest distance from a point C to a line segment AB in Euclidean geometry is the  perpendicular distance from the point C to the line segment AB

The line which best approximates the perpendicular line and therefore,

shortest distance from C to AB is the line segment CB

CB represents the shortest line and therefore distance from C to AB, that is

CB is shorter than line segment CA and which shows that it is shorter to go

from C to B, than from C to A or point C is closer to point B than point A

Three consecutive odd numbers sum to 1,245. What are the three numbers? ​

Answers

Answer:

413, 415, 417

Step-by-step explanation:

Answer:

414, 415, 416

Step-by-step explanation:

Consecutive numbers means they come one after another, like 1,2,3,4,5... So they all follow the formula x, x+1, x+2, x+3...x+n.

Since there are 3, we can say that x+(x+1)+(x+2)=1,245.

Simplify that to 3x+3=1,245, and then subtract 3 from both sides.

We get 3x=1,242. Divide that by 3, and you get x=414.

Add 1 and 2 to 414, and you get 414, 415, and 416.

You can add them up to check.

I need help finding the values of x and y!!

Answers

Answer:

x= 22

y = 35

Step-by-step explanation:

The base angles of a isosceles triangle are equal

3x-11 = 2x+11

Subtract 2x from each side

3x-2x -11 = 2x-2x+11

x-11 = 11

Add 11 to each side

x-11+11 = 11+11

x = 22

The sum of all the angles in a triangle is 180

3x -11 + 2x+11 + 2y = 180

Combine like terms

5x +2y = 180

5*22 + 2y = 180

110 + 2y = 180

Subtract 110 from each side

110+2y-110 = 180-110

2y = 70

Divide by 2

2y/2 =70/2

y = 35

Karen bought cupcakes for her sister's birthday party. 3 cupcakes had sprinkles on top. The other 27 cupcakes did not have sprinkles. What percentage of the cupcakes had sprinkles?

Answers

Answer:

10%

Step-by-step explanation:

so

3 cupcakes had sprinkles

27 didn't have sprinkles

which means that there are a total of 30 cupcakes, (because 3 + 27 is 30)

so then set up a proportion

part/whole = percent/one hundred

substitute in the given values

3 / 30= precent/100

simplify

1/10 = precent/100

you don't have to use cross products here because it is pretty obvious that 10 * 10 = 100 so then just multiply 1/10 by 10 and you get your answer

percent = 10
