Answer:
The correct answer is option C and D.
C). DC = 6√3
D). AC = 12√3
Step-by-step explanation:
3-4x+5=16-4x =>>kick 1. -4x to right side =>>
8=16-4x+4x=>> 8=16 that means question is wrong lol
Question should be 3+4x+5=2(8-2x) or 3-4x+5=2(8+2x)
Then the answer will be 8x=8 =>> x=1 :)
Answer:B

P = k + m + n Subtract m from both sides
P - m = k + n Subtract n from both sides
P - m - n = k Switch the sides to make it easier to read
k = P - m - n
