The value of x is 29.

Step-by-step explanation:

→ The angles arent congruent, they are supplementary.

→ Supplementary angles equals 180 degrees.

The equation looks look:

[tex]2x - 10 + 4x + 16 = 180[/tex]

→ Let's solve the equation.

[tex]2x - 10 + 4x + 16 = 180 \\ 6x + 6 = 180 \\ \frac{ \: \: \: \: \: - 6 = - 6}{ \frac{6x}{6} = \frac{174}{6} } \\ x = 29[/tex]

→ Therefore, the value of x is 29.

Polygon E’F’G’H’

is a dilation image of the polygon

EFGH

What is the scale factor of the dilation?

A.3

B.6

C.12

D.1/3

Answers

Answer:

The scale factor of the dilation is 3 A

Step-by-step explanation:

If a polygon dilated by a scale factor k, then the ratio between its sides and the corresponding sides of its image equals k The length of a vertical segment is the difference between the y-coordinates of its endpoints

In the given figure

∵ EFGH is a polygon

E = (-2, 1), H = (-2, -1)

∵ EH is a vertical side

→ By using the 2nd rule above

∴ The length of EH = 1 - (-1) = 1 + 1

The length of EH = 2

∵ E'F'G'H' is its image after dilation by scale factor k

E' = (-2, 5), and H' = (-2, -1)

∵ E'H' is a vertical side

∴ The length of E'H' = 5 - (-1) = 5 + 1

The length of E'H' = 6

→ By using the 1st rule above

∴  [tex]\frac{E'H'}{EH}[/tex] =  [tex]\frac{E'F'}{EF}[/tex] =  [tex]\frac{H'G'}{HG}[/tex] =  [tex]\frac{F'G'}{FG}[/tex] = k

∵  [tex]\frac{E'H'}{EH}[/tex] = k

∵ [tex]\frac{E'H'}{EH}[/tex] = [tex]\frac{6}{2}[/tex]

∴  [tex]\frac{E'H'}{EH}[/tex] = 3

k = 3

The scale factor of the dilation is 3

If you layered 100000 cubes to make one big cube what would the dimensions of the big cube

Answers

Answer:

The dimensions of the cube would be:

Base: 46,42 units approx.Height: 46,42 units approx.Width: 46,42 units approx.

Step-by-step explanation:

For this exercise, I suppose the measure of each cube is 1 unit, because there no says what is (you can replace it for ft, in, or another unit you need). How the big cube is formed by the 100.000 cubes smaller, and how a cube has its three measures equal: base, height, and width, you only need to obtain the cubic root of the total cubes (you use cubic root because you're gonna calculate a cube, for example, if you'd wanna calculate a square, you must obtain the square root of the total cubes):

[tex]\sqrt[3]{100.000} = 46,41588834[/tex]

How each cube measure is 1 unit, when you calculate the volume of the cube with the value obtained, you must obtain the total of the cubes:

Volume of the cube= base * height * width Volume of the cube= 46,41588834 * 46,41588834 * 46,41588834 Volume of the cube= 100.000

In this form, you know the answer 46,41588834 is the right answer. I use the number with just two decimals (46,42 approximately) but you can use the complete number if you need.

Write the equation of a line that passes through the point (-1,5) and has a slope of -7. Your answer should be given in the form y = mx + b

Answers

Answer:

The equation of a line that passes through the point (-1,5) and has a slope of -7 will be:

y = -7x-2

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

m is the slopeb is the y-intercept

Given

The point (-1, 5)Slope m = -7

substituting m = -7 and the point (-1, 5) in the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

5 = -7(-1) + b

5 = 7+b

b = 5-7

b = -2

Thus, the y-intercept is: b = -2

now substituting b = -2 and m = -7 in the slope-intercept form of the line equation

y = mx+b

y = -7x+(-2)

y = -7x-2

Therefore, the equation of a line that passes through the point (-1,5) and has a slope of -7 will be:

y = -7x-2

Select ALL that apply.​

Which expression uses the greatest common factor and the distributive property to rewrite the sum 64 + 32? 16(4+2) ​ 8(8+4) 32(2)+1 ​ 32(2+1) ​

Answers

Step-by-step explanation:

Since 64 = 32 * 2 and 32 = 32 * 1,

64 + 32 = 32(2 + 1).

16(4 + 2) is wrong as 4 and 2 have a GCF of 2.

8(8 + 4) is wrong as 8 and 4 have a GCF of 4.

32(2) + 1 is the wrong application of the distributive property.

Answer:

64+32=32(2+1) is greatest common factor

Step-by-step explanation:

Quadratic Function

It's given the length of a rectangular park is twice its width.

Let's call:

x = width of the rectangular park

2x = length of the rectangular park

The park is surrounded by a 3-foot-wide path. This path adds 3 ft twice to both dimensions, i.e.:

x+3+3=x+6 width of the park and the path

2x+3+3=2x+6 length of the park and the path

The total area is:

A=(x+6)(2x+6)

Operating:

[tex]A=2x^2+6x+12x+36[/tex]

[tex]\boxed{A=2x^2+18x+36}[/tex]
