Answer:
I believe the answer is n/3 + 15n.
Answer:
x=21
Step-by-step explanation:
4x+12=96
subtract 12 from both sides
4x=84
divide both sides by 4
x=21
You take 15*15 and you take 8*8 and then you add them both together
Let x be the number of rows and y be the number of trees per row.
x* y = 112
and y = 2x - 2
from first equation y = 112/x
so 112/x = 2x - 2
112 = 2x^2 - 2x
2x^2 - 2x - 112 = 0
x^2 - x - 56 = 0
(x - 8)(x + 7) = 0
x = 8 , - 7 (ignore the negative)
so the number of rows = 8
and number of trees per row = 112/8 = 14
Answer number of rows = 8 and number trees i each row = 14.
