Question

If B is the midpoint or AC, and AC = 8x -20, find BC.

Answer 1

so, BC = AC/2 = 2(4x - 10)/2 = 4x -10.

Answer 2

Answer: The Length of BC is 4x-10 units.

Explanation:

Since we have given that

Length of AC = 8x-20

And B is the mid point of AC.

And we know that Length of BC is the half of the length of AC.

So, Length of BC would be

`(8x-20)/(2)\\\\=(8x)/(2)-(20)/(2)\\\\=4x-10`

Hence, the Length of BC is 4x-10 units.
