Answer:
7x^(2)-3x+8
Step-by-step explanation:
(5x^(2) - 3x - 2) - (-2x^(2) - +10)
(5x^(2))- (-2x^(2))=7x^(2)
(- 2)-(+10)=+8
7x^(2)-3x+8

he initial number of trees was 204.
<h3>How to find the initial number of trees?</h3>
The first step to finding the initial number of trees is to write an equation that represents the situation.
- T is equal to the initial number of trees.
- 5 trees were removed = t - 5
- Each tree produces 210 oranges = (t-5) (210)
- The total of oranges is 41,780 = (t-5) (210)= 41,780
- (t-5) (210)= 41,780
- t-5= 41,780 / 210
- t-5 = 198.95
- t = 198.95 + 5
- t = 203.9
This number can be rounded as 204.
