40:260 is the ratio for this problem
(x²)-³ =<u> 1 </u> = <u> 1 </u> = <u> 1 </u><u /> = <u> 1 </u>
(x²)³ (x²)(x²)(x²) x² + ²+ ² x^6
An observation study is where nothing changes and you record what is seen. An experimental study you have a control group and a testable group.
The answer would be: .C. The groups in an experiment are chosen at random, but not in an observational study.
How am I supposed to answer that if I can't get the graph to you?
Answer: Here is the explanation. also it it +3y not -3y
Step-by-step explanation:
x+y+4+2y+1=x+3y+5 because
2y+y=3y
so now you have x+3y+4+1
4+1=5
now you have: x+3y+5
if you do not understand, What i am trying to say is, you need to add all of the same things.
