Answer:
5k²+8k+3
Step-by-step explanation:
5k²+5k+3k+3
5k²+8k+3
Answer:
what is that
Step-by-step explanation:
A direct variation means that y=kx, where k is constant.
-12=k(-4)
3=k
Plug in the known y value
24=3x
8=x
Final answer: 8
-3.5(2-3n)-2.5n=-7+10.5n-2.5n
=-7+8n
So the answer is B

all you have to do next is add all of them in one equation and equate them to 18
when you find x, replace in each expression to get your answers
