In an orange grove, three are 10 more trees in each row than there are rows. How many rows are there if there are 96 trees in the grove?

Answer 1

10 more trees per row than there are rows

96 total trees

how many rows??

96 = rows times trees per row = x(10+x) = x^2 +10x

x^2 +10x = 96

x^2 +10x +25 = 96+25 = 121

x+5 = sqr121 = 11

x = 11-5 = 6 rows of 16 trees each

6 times 16 = 96
