Answer: x= 21.20 and y =6.47 (wondering if the numbers written in were given? The lengths seem weird. For the top triangle, the drawing shows one length as 8, the other as 5, but clearly the "5" length is longer than the "8" length shown in the picture?)

Step-by-step explanation:

5/y = 17/22; now cross multiply:

17y = 5(22); 17y = 110; y = 6.47

Now for x:

8/6.47 = (8 + x-2)/22;

8/6.47= (6 + x)/22; now cross multiply:

6.47(6 + x) = 8(22)

38.82 + 6.47x = 176

6.47x = 137.18; divide by 6.47:

x = 21.20

Answer:

x = 21.2

y = 6.470588235

Step-by-step explanation:

We can use similar triangles and proportions to solve.  

KJ              KL

---------- = ----------

JM              MN

Substituting what we know

5          y

----- = ----------

5+12          22

Using cross products

5*22 = (12+5)y

5*22 = (17)y

Divide each side by 17

5*22/17  =17y/17

110/17 = y

6.470588235 =y

KJ              JL

---------- = ----------

JM              JN

Substituting what we know

5          8

----- = ----------

5+12      8+x-2

Using cross products

5 *(8+x-2) = 8(5+12)

5*(6+x) =8*17

Distribute

30+5x = 136

Subtract 30

30-30 +5x = 136-50

5x = 106

Divide by 5

5x/5 = 106/5

x =21.2

The length of a rectangle is 4 less than twice the width. If the perimeter of the rectangle is 130, find the length of the recta
Alchen [17]

Answer:

Let L be the length of the rectangle and w be the width of the rectangle.

"The lenght of a rectangle is one less than twice the width" means L=2W-1

Using perimeter formula of a rectangle which is P=2(L+W) you have:

P=2(L+W)

130=2(2W-1+W)

Solve equation above to find W

130=2(3W-1)

130=6W-2

130+2=6W

132=6W

W=22

From here you find L=2W-1=2x22-1=43

Only thing left is to find area A=LxW

The figures below are similar.
Dafna1 [17]

Answer:

  a) 2.5

  b) 6.25

Step-by-step explanation:

For similar figures, the ratio of any corresponding linear dimensions is the same. The ratio of areas is the square of that.

<h3>Application</h3>

The ratio of linear dimensions, larger to smaller, is ...

  (30 yd)/(12 yd) = 2.5

<h3>a) Perimeter</h3>

Perimeter is a linear dimension, the sum of side lengths. The ratio of perimeters is 2.5.

<h3>b) Area</h3>

The ratio of areas, larger to smaller, is the square of the scale factor for side lengths:

  (2.5)² = 6.25

The ratio of the areas of the larger to smaller figure is 6.25.
