Answer:

see explanation

Step-by-step explanation:

n² - 16 ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b) , then

n² - 16

= n² - 4²

= (n + 4)(n - 4)

cannot be (n + 8)(n - 8)

= n² - 64

Answer/Step-by-step explanation:

Let's first solve [tex](n+8)(n-8)[/tex]

Distribute

[tex]n(n-8)+8(n-8)[/tex]

Distribute

[tex]n^2-8n+8(n-8)[/tex]

Distribute

[tex]n^2-8n+64[/tex]

Combine like terms

[tex]n^2-64[/tex]

Therefore n2-16 is not equal to (n+8)(n-8) because (n+8)(n-8) is equal to n^2-64.

Answer:y=14x+7

Step-by-step explanation:

Answer:

[tex]2*2[/tex]  ← equals 4

[tex]-4[/tex]  ← equals 0

[tex]+14[/tex]  ← equals 14  

↑ This equation means multiply 2 by itself one time, subtract 4, and add 14. Let's find the value.

Therefore,

the value is 14. Result may vary with x. There are ways to factorize this, but I did not want to confuse you. [tex]:)[/tex]

Answer:

length = 15

Width = 9

Step-by-step explanation:

In a rectangle opposite sides are equal.

5x - y- 8 =3x +5y + 4

5x - 3x  -y - 5y = 4 + 8

2x - 6y = 12

Divide the entire equation by 2

x  - 3y = 6  --------------(I)

3x + y - 4 = 2x - 6y - 3

3x - 2x + y + 6y = -3 + 4

x + 7y = 1 -------------(II)

Multiply equation (II) by (-1)

(I)            x - 3y = 6

(II)*(-1)    -x - 7y = -1   {Now add. 'x' will be eliminated}

                  -10y= 5

                      y = 5/(-10)

                     y = -0.5

Plugin y = -0.5 in equation (I)

x - 3*(-0.5) = 6

x  + 1.5 = 6

        x = 6 - 1.5

        x = 4.5

Length = 5x - y - 8

           = 5*4.5 - (-0.5) - 8

           = 22.5 + 0.5 - 8

            = 23 - 8

Length = 15

Width = 2x - 6y - 3

         = 2*4.5 - 6*(-0.5) - 3

         =  9 + 3 - 3

Width = 9

The height of the ceiling is 162.31 meters

The situation will form a right angle triangle.

Right triangle has one of its angles as 90 degree. Therefore, the sides can be found using trigonometric ratios

The triangle formed, the theodolite distance from the spotlight is the  adjacent side. Therefore,

tan 62.7 = opposite / adjacent

tan 62.7 = x / 83

cross multiply

x = 83 × tan 62.7

x = 160.809554025 m

Step-by-step explanation:

The starting point for an e=inequality will have either an empty of filled-in circle.  When empty, it signifies that the exact point is NOT included.  If the inequality is x < 2, for example, the line would begin at 2, but marked with an empty circle.  If, however, the inequality is x =< 2, then the circle is filled in, signifying that the number 2 is included in the set.

Answer:

Answer:

x = 1

Step-by-step explanation:

2x +4 (3 - 2x) = 3(2x + 2)/6 + 4

2x+12-8x = (6x+6)/6 +4

-6x + 12 = x+1+4

12-5 = 7x

7x = 7

x=1

Hope this helps!

2x + 4(3-2x) = 3(2x+2)/6 +4

Break the brackets :

2x + 12 - 8x = (6x+6)/6 + 4

2x + 12 - 8x = x + 5

2x + 12 - 8x - (x+5) = 0
2x + 12 - 8x - x - 5 = 0
-7x + 7 = 0

-7x = -7
x = 1.

Answer:

[tex](x-5)(x-5)[/tex]

Step-by-step explanation:

We need to find two numbers that multiply to get 25 and have a sum of -10...

(-5)(-5)=25

-5-5=-10

We can split -10x into -5x and -5x:

[tex]x^2-5x-5x+25[/tex]

Factor each half of the expression separately:

[tex]x(x-5)-5(x-5)[/tex]

Since both x and -5 are being multiplied by (x-5), we can combine them to get:

[tex](x-5)(x-5)[/tex]

The area of Jill's soccer net is 3 times larger than area of Peter's soccer net.

The area of Peter's soccer net is determined by using area of rectangle as shown below;

A1 = 5.5 ft x 4 ft

A1 = 22 ft²

A2 = 5.5 ft x 12 ft

A2 = 66 ft²

A2/A1 = 66/22

A2/A1 = 3

Thus, the area of Jill's soccer net is 3 times larger than area of Peter's soccer net.

Step-by-step explanation:

All the faces are the same and 8 vertices would make a cube.

Answer: cube

All of its faces are congruent, it has 8 vertices and it is a 3D figure, so it is a cube.

A cube is a three-dimensional geometric shape that meets the given criteria.

Let's break down the reasons why:

This means that each face has the same shape and size, and all angles within the cube are right angles (90 degrees).

Each vertex is the point where three edges of the cube meet.

It has length, width, and height, making it a 3D geometric figure.

A cube is a special type of rectangular prism where all sides are equal in length.

Its symmetry and regularity in terms of congruent faces, edges, and vertices make it a fundamental and easily recognizable three-dimensional shape.
