Answer:

n = 3.17

Step-by-step explanation:

Given:

8n − 6 = 2n + 13

Collect like terms

8n - 2n = 13 + 6

6n = 19

Divide both sides by 6

n = 19/6

= 3.167

Approximately to the nearest tenth

n = 3.17

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
