Alright, lets gets tarted.
Suppose there are x rows of tomato plants Krystyn make.
Again suppose there are n plants in each row.
We could find total plants by multiplying number of plants in each row with number of rows.
Hence total number of plants will be = [tex] x * n [/tex]
But as per question, total number of plants are 54. It means
[tex] x * n = 54 [/tex]
Now, the number of plants in each row was 3 more than the number of rows means
[tex] n = x + 3 [/tex]
Putting this value of n in first equation we made
[tex] x * (x+3) = 54 [/tex]
[tex] x^{2} + 3x = 54 [/tex]
Subtracting 54 in both sides
[tex] x^{2} + 3x - 54 = 54 - 54 [/tex]
[tex] x^{2} + 3 x - 54 = 0 [/tex]
Factoring
[tex] (x-6)(x+9) = 0 [/tex]
Means x = 6 or x = -9
The number of rows can not be negaive.
Hence x = 6
It means number of rows of tomato plants will be 6. : Answer
Hope it will help :).
