In trapiziod ABCD with bases AB and DC , diagonals intersect at point O. Find the length of diagonal BD, if BO=6 cm and A/O=3/1
ElenaW [278]

Answer:

the length of the diagonal BD is 8 cm

Step-by-step explanation:

The computation of the length of diagonal BD is as follows

Here the trapezoid diagonals divides each other in an equivalent ratio

So, equation would be

AO ÷ OC = OB ÷ OD

Now put there values to the above equation

3 ÷ 1 = 6 ÷ OD

3OD = 6

Now divided it by 3 in both the sides

OD = 2

Now the BD would be

= BO + OD

= 6 +  2

= 8 cm

hence, the length of the diagonal BD is 8 cm

The area of a parallelogram is 96 cm squared the height is 4 cm less than the length what is
andrey2020 [161]
Area of paralellogram=legnth times height

l=legnth
h=height
area=96

lh=96

h is 4 less than l
h=-4+l
sub
l(-4+l)=96
-4l+l^2=96
minus 96 both sides
l^2-4l-96=0
factor
(l-12)(x+8)=0
set to zero
l-12=0
l=12

l+8=0
l=-8, imossible, legnth cannot be negative, disreagard this soultion

legnth=12cm

Write the slope-intercept form of the equation of the line through the given points.
MatroZZZ [7]

Answer:

y = x-4

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

   = ( -3 -1)/( 1 - 5)

   = -4/-4

   = 1

Then using slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = 1x+b

Substitute one of the points in

1 = 5 +b

1-5 = b

-4 =b

y = x-4
