Answer is 25 degrees.

Answer:

k=12

Step-by-step explanation:

Top left angle is 84 degrees also, due to alternate interior angles cut by the transveral.

2 sides are congruent, leaving bottom left corner angle also 84 degrees.

Write an equation to solve for k:

84+84+k=180

simplify

168+k=180

subtract 168 from both sides

k=12

Answer:

Yes you are correct, the answer is D

Step-by-step explanation:

the answer is still 420 regardless if you do :

\(42*(3.5+1.3+5.2)\\\)

or

\((42* 3.5)+(42* 1.3)+(42 *5.2)\)

Answer:

Note that both the x and y coordinates are multiplied by the SAME value, k. Given ΔDEF with center of dilation the origin (0,0) and scale factor of 2, plot ΔD'E'F'. As shown in the formula above, multiply each x and y coordinate value by the scale factor of 2 to find the new coordinates

Answer:

Step-by-step explanation:

Assuming 280 miles is the total distance travelled:

Let b = boat speed in still water

Let c = current speed.

For the downstream trip the speed is b + c. In 7 hours at the speed of (b + c) mph the boat travels 140 miles.

7(b + c) = 140 .............(1)

For the upstream trip the speed is b - c. In 14 hours at the speed of (b - c) mph the boat travels 140 miles.

14(b - c) = 140 ............(2)

The left hand sides of equations (1) and (2) are equal. Therefore we can write

7b + 7c = 14b - 14c ...........(3)

Rearranging equation (3) we get

21c = 7b

c = b/3 .......................(4)

The value for c obtained in equation (4) should now be substituted into equation (1) which can then be solved to find the value of b.

Answer:

80 ft2

First let's find the total area of the wall: 12 x 8 = 96. Then, we need to subtract out the window. To find the area of the wall, we'll need to find the area of the window and subtract it from the total area of the wall: 4 x 8 = 32 | 96 - 32 = 64. However, I am assuming the height of the window is 8 feet. If the window is 1 foot tall, the answer is 92 feet. If the window is 4 feet tall, the answer is 80 feet.

(The first and last answers are incorrect) As there is no picture provided, as I am assuming there is a picture, please follow my instructions left for you above as to what the answer would be depending on the height of the window.

Answer:

x = -4

Step-by-step explanation:

Make x variable on one side.

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

Simplify.

x/3 - 2/3 = 2x/2 + 2

x/3 - 2/3 = x + 2

Add 2/3 and -x on both sides.

x/3 - x = 2 + 2/3

-2/3x = 8/3

Multiply -3/2 on both sides.

x = -4

Answer:

x=-4

Step-by-step explanation:

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

We can use cross products

(x-2) *2 = 3(2x+4)

Distribute

2x-4 = 6x+12

Subtract 2x from each side

2x-4-2x = 6x-2x+12

-4 = 4x+12

Subtract 12

-4-12 = 4x+12-12

-16 = 4x

Divide by 4

-16/4 = 4x/4

-4 =x

I learned this formula in math last year

Answer:

X=4 or X=-2

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant   1 • -8 = -8  

Step-2 : Find two factors of  -8  whose sum equals the coefficient of the middle term, which is   -2 .

     -8    +    1    =    -7  

     -4    +    2    =    -2    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -4  and  2  

                    x2 - 4x + 2x - 8

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-4)

             Add up the last 2 terms, pulling out common factors :

                   2 • (x-4)

Step-5 : Add up the four terms of step 4 :

                   (x+2)  •  (x-4)

            Which is the desired factorization

Equation at the end of step

1

:

 (x + 2) • (x - 4)  = 0  

STEP

Theory - Roots of a product

2.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation:

2.2      Solve  :    x+2 = 0  

Subtract  2  from both sides of the equation :  

                     x = -2

Solving a Single Variable Equation:

2.3      Solve  :    x-4 = 0  

Add  4  to both sides of the equation :  

                     x = 4

Supplement : Solving Quadratic Equation Directly

Solving    x2-2x-8  = 0   directly  

Earlier we factored this polynomial by splitting the middle term. let us now solve the equation by Completing The Square and by using the Quadratic Formula

Parabola, Finding the Vertex:

3.1      Find the Vertex of   y = x2-2x-8

Parabolas have a highest or a lowest point called the Vertex .   Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) .   We know this even before plotting  "y"  because the coefficient of the first term, 1 , is positive (greater than zero).  

Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two  x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.  

Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.  

For any parabola,Ax2+Bx+C,the  x -coordinate of the vertex is given by  -B/(2A) . In our case the  x  coordinate is   1.0000  

Plugging into the parabola formula   1.0000  for  x  we can calculate the  y -coordinate :  

 y = 1.0 * 1.00 * 1.00 - 2.0 * 1.00 - 8.0

or   y = -9.000

Parabola, Graphing Vertex and X-Intercepts :

Root plot for :  y = x2-2x-8

Axis of Symmetry (dashed)  {x}={ 1.00}  

Vertex at  {x,y} = { 1.00,-9.00}  

x -Intercepts (Roots) :

Root 1 at  {x,y} = {-2.00, 0.00}  

Root 2 at  {x,y} = { 4.00, 0.00}  

Solve Quadratic Equation by Completing The Square

3.2     Solving   x2-2x-8 = 0 by Completing The Square .

Add  8  to both side of the equation :

  x2-2x = 8

Now the clever bit: Take the coefficient of  x , which is  2 , divide by two, giving  1 , and finally square it giving  1  

Add  1  to both sides of the equation :

 On the right hand side we have :

  8  +  1    or,  (8/1)+(1/1)  

 The common denominator of the two fractions is  1   Adding  (8/1)+(1/1)  gives  9/1  

 So adding to both sides we finally get :

  x2-2x+1 = 9

Adding  1  has completed the left hand side into a perfect square :

  x2-2x+1  =

  (x-1) • (x-1)  =

 (x-1)2

Things which are equal to the same thing are also equal to one another. Since

  x2-2x+1 = 9 and

  x2-2x+1 = (x-1)2

then, according to the law of transitivity,

  (x-1)2 = 9

We'll refer to this Equation as  Eq. #3.2.1  

The Square Root Principle says that When two things are equal, their square roots are equal.

Note that the square root of

  (x-1)2   is

  (x-1)2/2 =

 (x-1)1 =

  x-1

Now, applying the Square Root Principle to  Eq. #3.2.1  we get:

  x-1 = √ 9

Add  1  to both sides to obtain:

  x = 1 + √ 9

Since a square root has two values, one positive and the other negative

  x2 - 2x - 8 = 0

  has two solutions:

 x = 1 + √ 9

  or

 x = 1 - √ 9

Solve Quadratic Equation using the Quadratic Formula

3.3     Solving    x2-2x-8 = 0 by the Quadratic Formula .

According to the Quadratic Formula,  x  , the solution for   Ax2+Bx+C  = 0  , where  A, B  and  C  are numbers, often called coefficients, is given by :

           - B  ±  √ B2-4AC

 x =   ————————

                     2A

 In our case,  A   =     1

                     B   =    -2

                     C   =   -8

Accordingly,  B2  -  4AC   =

                    4 - (-32) =

                    36

Applying the quadratic formula :

              2 ± √ 36

  x  =    —————

                   2

Can  √ 36 be simplified ?

Yes!   The prime factorization of  36   is

  2•2•3•3  

√ 36   =  √ 2•2•3•3   =2•3•√ 1   =

               ±  6 • √ 1   =

               ±  6

So now we are looking at:

          x  =  ( 2 ± 6) / 2

Two real solutions:

x =(2+√36)/2=1+3= 4.000

or:

x =(2-√36)/2=1-3= -2.000
