PLEASE HELP! HURRY! since its 2 questions, ILL GIVE MORE POINTS!

Which of these equations has no solution?
A. m = 0
B. m = m
C. 2m + 1 = m – 2
D. m + 4 = m – 4

A. m = 0 || This is incorrect, because m being equal to 0 is a solution in and of itself.

B. m = m || This is incorrect, because m being equal to itself means that there are an infinite number of solutions.

C. 2m + 1 = m - 2 | m = -3 || This is incorrect, because m can be solved for and has a solution.

D. m + 4 = m - 4 | 4 = -4 || This is correct because 4 is not equal to -4, and thus there is no solution.

Hope this helps!! :)

answer: 38.47 is your answer

step-by-step explanation: hope i you and who ever sees this answer have a great rest of your day : )

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
