Question

B is the midpoint of A and C. If BC=3x2^2, and AC=54, find the value of x.

Answer 1

x = 3

Answer 2

Explain how if I substitute x with 3, it would equal 54?

Answer 3

ac= 54 and bc is mid of ac so bc - 54/2-27
and acc to eq bc=3x^2=27

divide bothsides by 3
(3x^2)/3=27/3

x^2=9
applying square root

x=3
