Answer:
Xavier should not give the flea medication to group D.
Step-by-step explanation:
In any testing of a drug normally two groups are formed.
One group is given the named as experiment group and other group is not given any medication named as controlled group.
After the completion of testing results of these two groups (experimental and controlled) are compared to find the efficacy of the drug.
Hence Xavier should not give the flea medication to group D. It should be a controlled group.
It's No, because group D should be the control group. A control group means a group that doesn't receive the treatment so the two can be compared.

21 < 13 + x
8 < x
If x is the longest side:
x < 13 + 21
x < 34
Therefore, 8 < x < 34.
