Answer:
C
Step-by-step explanation:
C is the dependent variable because it depends on the other side of the equation. S can be anything, it doesn't matter what the others are. However, whatever c is depends on what s is, and changes depending on what you have for s.
I am almost positive that it is A. Because the lines mean absolute value so that would change the negative numbers to positive. And since there is not a line under the less than sign 4 can not be in the answer.
Answer:
9
Step-by-step explanation:
DB^2=AD^2+AC^2
15^2=12^2+AC^2
AC^2=225-144
AC^2=81
AC=√81
AC=9

Step-by-step explanation:
thats took a while lol
First you add like terms, so in this case it would be 2x+3x, which would together make 5x=10. Then to get x isolated divide 10 by 5 and x=2
