Answer 1

Given:

An orchard has 864 orange trees.

The number of rows exceeds the number of trees per row by 5.

To find: The number of trees in a row

Explanation:

Let x be the number of trees in a row.

So, x+5 be the number of rows.

Let us frame the equation as follows.

$\begin{gathered} x(x+5)=864 \\ x^2+5x=864 \\ x^2+5x-864=0 \\ x^2+32x-27x-864=0 \\ x(x+32)-27(x+32)=0 \\ (x-27)(x+32)=0 \\ x=27,\text{-}32 \end{gathered}$

Hence, the number of trees in a row is 27.

Final answer: There are 27 trees in each row.
