Answer:
x=4
Step-by-step explanation:
-3x+12-12=x-4-12
-3x=x-16
-3x-x=x-16-x
-4x=-16
-4 divided by -16
x=4
Answer:
A and B
Step-by-step explanation:
using the law of exponents
•
=
, hence
=
→ A
note that (- 3)² = 9 = 3², hence
= (3²)³ =
→ B
Since BD is the perpendicular bisector of AC, then AB = BD, so:
6x = x+15
5x=15
x=3
CB = 3+15 = 18
