76 inches if the length is two more than five times the width what is the length

Mathematics

Vadim26 [7]3 years ago

Answer:

32 inches

Step-by-step explanation:

Assuming 76 inches is perimeter, we'll say that w is width

Length = 5w + 2

Perimeter = w + w +  (5w+2) + (5w+2) = 76 inches

12w + 4 = 76

Subtract 4 on both sides

12w = 72

Divide 12 on both sides

w = 6

---

If the width is 6, then 5w + 2 = 5(6) + 2 = 30 + 2 = 32

---

Width - 6 inches

Length - 32 inches

Perimeter - 76 inches

Write the equation of the line that passes through the points (-3, - 5) and (-9,3). Express your answer in
Leokris [45]

that's the answer

Step-by-step explanation:

slope =  \frac{y2 - y1}{x2 - x1}  \\ =  \frac{3 -  - 5}{ - 9 -  - 3} =  \frac{8}{ - 6} \\  \frac{y - 3}{x -  - 9} =  \frac{8}{ - 6}  \\  - 6(y - 3) = 8(x -  - 9) \\  - 6y  + 18 = 8x + 72 \\  - 6y = 8x + 72 -18 \\  - 6y = 8x + 54 \\  \frac{ - 6y}{ - 6} =  \frac{8x}{ - 6} +  \frac{54}{ - 6} \\ y =  \frac{8x}{ - 6}  - 9

Area of a Triangle
jek_recluse [69]

Answer:

3.51 (round to the nearest hundreds)

Step-by-step explanation:

PART A

slope of the line passing through AC : (6-1)/(1-2) = 5/-1 = -5

equation of the line passing through B and perpendicular to AC:

y-3 = 1/5(x-3)

y-3 = 1/5x -3/5

y = 1/5 x - 3/5 + 3

y = 1/5 x + (-3+15)/5

y = 1/5 x + 12/5

PART B

line that passes through the points A and C

y-1 = -5(x-2)

y = -5x+10 + 1

y = -5x + 11

Interception of the lines

y = 1/5x + 12/5

y = -5x + 11

-5x + 11 = 1/5x + 12/5

-25x +55 = x + 12

26x = 43

x = 43/26

y = -5(43/26) + 11

y= -215/26 + 11

y = (-215+286)/26 = 71/26

D (1.65, 2.73)

PART C

AC = \sqrt{(1-2)^2 + (6-1)^2} = \sqrt{1 + 25} = \sqrt{26} = 5,09902

BD = \sqrt{(3-1.65)^2 + (3-2.73)^2} = 1,376735

PART D

AREA = (5,09902 * 1.376735)/2 = 3,509999
