Answer:L= 3W

Perimeter = 2(l+w) = 40

 

2(3w+w) = 40

 

2*4w = 40

8w =40

w = 5

l = 3*5 = 15

Hope I helped

HELP!!!!!
choli [55]

Answer:

  x = 64 m

Step-by-step explanation:

The scale is proportional to the actual:

  (6 m)/(3/4 cm) = x/(8 cm)

Multiplying by 8 cm, we get ...

  x = (8 cm)·(6 m)/(3/4 cm)

  x = 64 m . . . . the width of the actual wall

Determine the point of intersection of right bisectors in a triangle ∆ with vertices A (-3, 5), B (1, 1) and (−7, −3). Find the
iris [78.8K]

Answer:

Point of intersection (-11/3 , 1/3)

All distances from the vertices are \frac{10\sqrt{2} }{3}

Step-by-step explanation:

The vertices of the triangle is A(-3,5) , B (1,1) and C (-7,-3)

We need to find the perpendicular bisector of the triangle first

let's take one side connecting A and B

mid point of A and B = (-1,3)

Slope of the line joining A and B = -1

slope of perpendicular to line joining A and B = 1

equation of line passing through (-1,3) with slope 1

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

y -3 = x+1

x-y = -4 ............(1)

similarly

mid point joining B and C = (-3,-1)

slope perpendicular to line joining B and C  =  -2

Equation of perpendicular bisector of line joining B and C =

y +1 = -2(x +3 )

y+1 = -2x -6

2x+y = -7 ..........(2)

On solving 1 and 2

x= -11/3 , y= 1/3

Distances

From A = \frac{10\sqrt{2} }{3}

From B = \frac{10\sqrt{2} }{3}

From C = \frac{10\sqrt{2} }{3}
