Question

Point C is on line segment BD. Given BD=2x, CD=8, and BC=x determine the numerical length of BD.

Answer 1

BD = 16

Explanation:

It is given that, C is on the line segment BD. BD = 2x, CD = 8 and BC = x

We need to find the value of BD.

BD = BC + CD

Putting all the values,

2x = x + 8

taking like terms

x = 8

Put the value of x in BD.

BD = 2(8)

BD = 16

Hence, the length of BD = 16
