Jamin wants to paint a wall in his bedroom. In order to know how much paint to buy, he first needs to know the approximate area. There is a window in the middle of the wall, so he'll only need to paint the shaded part shown. How many square feet is just the window? [Note: The wall and window are both rectangular.]

Answer:

[tex]1 + \frac{3}{x} [/tex]

Step-by-step explanation:

1) Rewrite x² - 9 in the form a² - b² where, a = x and b = 3.

[tex] \frac{ {x}^{2} - {3}^{2} }{ {x}^{2} - 3x} [/tex]

2) use difference of squares: a² - b² = ( a + b ) (a - b).

[tex] \frac{(x + 3)(x - 3)}{ {x}^{2} - 3x} [/tex]

3) Factor out the common term x.

[tex] \frac{(x + 3)(x - 3)}{ x(x - 3)} [/tex]

4) Cancle out x - 3 .

[tex] \frac{x + 3}{x} [/tex]

5) Simplify.

[tex]1 + \frac{3}{x} [/tex]

Therefor, the answer is 1 + 3/x.

Answer: 1. x = 32, 2. x = 16, 3. x = 77

Step-by-step explanation: All of these angles are 90 degree angles, therefore by subtracting the known term from 90, you are able to find the value of x. I hope that this helps :)

Answer:

Might be 0.9821

Answer:

the sum of exterior angle of a polygon is always 360 degree.

therefore,

xº+ 2x°+ 4x°+ 6x°+ 8x°+ 9x° +10x° = 360°

40x = 360°

x = 360/40 = 9

x = 9

The sum of the exterior angles of a polygon is 360 degrees, so the value of x is 9

The exterior angles of the polygon are given as:

xº, 2x°, 4x°, 6x°, 8x°, 9x°  and 10x°

The exterior angles of a polygon add up to 360 degrees.

So, we have:

[tex]x\º+ 2x\°+ 4x\°+ 6x\°+ 8x\°+ 9x\° +10x\° = 360\°[/tex]

Evaluate like terms

[tex]40x\° = 360\°[/tex]

Divide both sides of the equation by 40

[tex]x\° = \frac{360\°}{40}[/tex]

Divide 360 by 40

[tex]x\° = 9[/tex]

Rewrite as:

[tex]x = 9\°[/tex]

Hence, the value of x is 9

If they are each rotated 180° about the origin, they will not remain parallel.

If they are each translated 7 units to the left, they will remain parallel.

If they are each rotated 270° about the origin, they will remain parallel.

Step-by-step explanation:

I got them!!!!!!!!!!!!!!!!

If they are each rotated 180° about the origin, they will not remain parallel, If they are each translated 7 units to the left, they will remain parallel and  If they are each rotated 270° about the origin, they will remain parallel are true statements.

Coordinate geometry (or analytic geometry) is defined as the study of geometry using the coordinate points.

Parallel lines are coplanar infinite straight lines that do not intersect at any point.

Among the given statements the following are true.

If they are each rotated 180° about the origin, they will not remain parallel.

If they are each translated 7 units to the left, they will remain parallel.

If they are each rotated 270° about the origin, they will remain parallel.

Hence, If they are each rotated 180° about the origin, they will not remain parallel, If they are each translated 7 units to the left, they will remain parallel and  If they are each rotated 270° about the origin, they will remain parallel are true statements.

Answer:

Step-by-step explanation:

You are given two points whose y values are the same. There is no need to use the distance formula. The x values alone will give you the length of the line.

to get to the y axis you have to go 12 units to the right.

To get from the y axis to 9, you have to go 9 more units to the right.

The total is 9 + 12 = 21

If you insist to see this done with the formula, it would look like this.

d = sqrt( y2 - y1)^2 + (x2 - x1)^2 )

y2 = 6

y1 = 6

x2 = -12

x1 = 9

d = sqrt ( (6 - 6)^2 + (-12 - 9)^2 )

d = sqrt( 0 + ( -21 )^2 )

d = sqrt( 441)

d = 21 the same thing you got just be reasoning it out.

The first method works only if either both xs are the same or both ys are the same.

Answer:

Step-by-step explanation:

The point-slope form of the equation that describes the line with a slope of m and including the point (x₀, y₀) is: y - y₀ = m(x - x₀)

m = 6

(1, 10)  ⇒    x₀ = 1,  y₀ = 10

Therefore:

y - 10 = 6(x - 1)          ← the point-slope form

y - 10 = 6x - 6       {add 10 to both sides}

y = 6x + 4               ← the slope-intercept form

Answer:

C = 39

Step-by-step explanation:

From the question given above, the following data were obtained:

A = 2x + 108

B = x + 33

C =?

Next, we shall obtain an expression for C. This can be obtained as follow:

A + B + C = 180 (sum of angles in a triangle)

2x + 108 + x + 33 + C = 180

2x + x + 108 + 33 + C = 180

3x + 141 + C = 180

Make C the subject by rearranging

C = 180 – 141 – 3x

C = 39 – 3x

Next, we shall determine the value of x. This can be obtained as follow:

A = 2x + 108

B = x + 33

C = 39 – 3x

A + B + C = 180

2x + 108 + x + 33 + 39 – 3x = 180

2x + x – 3x + 108 + 33 + 39 = 180

3x – 3x + 180 = 180

3x – 3x = 180 – 180

3x – 3x = 0

x(3 – 3) = 0

x(0) = 0

x = 0

Finally, we shall determine C. This can be obtained as follow:

C = 39 – 3x

x = 0

C = 39 – 3(0)

C = 39 – 0

C = 39
