I need help with geometry

Answer:

Step-by-step explanation:

2, -3 , -8 , -13 , - 18 .............

This is an arithmetic sequence.

First term = a = 2

Common difference = Second term - first term

                                 = -3 - 2 = -5

Nth term = a + (n - 1)*d

               = 2 + (n - 1)*(-5)

               = 2 + n*(-5) - 1 *(-5)

               = 2 - 5n + 5

             = 7 - 5n

n = 19,

19th term = 7 - 5*19

               = 7 - 95

               = - 88

n = 21,

21st term = 7 - 5*21

               = 7 - 105

               = -98

Answer:

25.5 u²

Step-by-step explanation:

Find the area of the rectangle, then the area of the triangle. To get the final area, add them together.

Rectangle: 3 x 5 = 15

Triangle: 3 x 7 ÷ 2 = 10.5

Total: 15 + 10.5 = 25.5 u² (you put it in units since you don't know the measure, e.g. cm, m, km...)

Answer:

7

Step-by-step explanation:

Plug it in.....

h(0) = 2.5 * 0 + 7 = 7

(x-4)(x+9) is equivalent to x^2+5x-36

all you need to do is factor the equation

Answer:

$32

if you do 33.60*100=3,360

then you do 3,360/105 it would be 32

Answer:

there is no picture..

Step-by-step explanation:

The first graph shows a dilation.

Option A is the correct answer.

Dilation is a transformation that changes the size of an object without changing its shape.

It involves scaling an object by a factor called the scale factor.

We have,

First graph:

The initial shape is a rectangle.

The dilated shape is also a rectangle.

So it is a dilation.

Second graph:

The initial shape is a square.

The dilated shape is a rectangle.

So it is not a dilation

Third graph:

The initial shape is a rectangle.

The dilated shape is also a rectangle but the size is not dilated in similar dimensions.

So it is not a dilation.

Thus,

The first graph shows a dilation.

Answer:

[tex]266[/tex] [tex]\frac{2}{3}[/tex] [tex]yards[/tex]

Step-by-step explanation:

1. Approach

First, convert the dimensions of the room from feet to yards. Remember, the conversion rate between feet and yards is, [tex]3feet=1yard[/tex]. Next, find the area of the room by multiplying the length by the width.

2. Convert the unit of measurement

The measurement unit is given in feet, one must convert it into yards. The conversion rate between yards and feet is, [tex]3feet=1yard[/tex].

[tex]60feet=20yards\\\\40feet=13\frac{1}{3}yards[/tex]

3. Find the area of the room

Now multiply the length by the width to find the area of the room.

[tex]20yards*13\frac{1}{3}yrads\\\\= 20 * \frac{40}{3}\\\\=\frac{800}{3}\\\\= 266\frac{2}{3}_{.}yards^{2}[/tex]

Answer:

33. m = 18

34. b = -29

35. w = -6

36. t = 8

Step-by-step explanation:

33. -3 + m = 15

    +3           +3

      m = 18

34. 9 + b = -20

      -9        -9

     b = -29

35. -7 - w = -1

           +w      +w

      -7 = -1 + w

              +1

       -6 = w   w = -6

36.  -4 -t = -12

           +t        +t

       -4 = -12 +w

       +12  +12

       8 = w  w = 8

Step-by-step explanation:

consider 61°=m angle 8

angle 1=angle 8........ corresponding angle

angle 1=61°

angle 2+angle 1=180°.........angles in linear pair

180-61

angle 2=119°

angle 3=angle 8 alternate angle

angle 3=61°

angle 4=angle 2............ opposite angles

angle 4=119°

angle 5=angle 4......... alternate angles

angle 5=119°

angle 6=angle 8......... opposite angles

angle 6=61°

angle 7=angle 5.......... opposite angles

angle 7=119°

Answer:

x = 27.8

y = 35

Step-by-step explanation:

∡D ≅ ∡A, therefore:

65 = 2y - 5

70 = 2y

y = 35

EF ≅ BC, therefore:

2x + y = 90.6

2x + 35 = 90.6

2x = 55.6

x = 27.8
