Answer:
9
Step-by-step explanation:
For this problem, you would use the GCF
Find the GCF of 45, 81, 63
GCF(45, 81, 63) = 9
45 = 9 * 5
81 = 9 *9
63= 9 * 7
Since 5, 9, 7 have no common factors, the GCF has to be 9.
This means that the greatest number of plants he can put in each row is 9.
The number of rows he uses for each plant will (obviously) vary.
ANSWER
See below
EXPLANATION
Given

and



Expand:



Since the denominators are the same, they will cancel out,

First subtract the 7 from both sides and that would equal 2x+9=2x then subtract 2x and the answer is 9
