Answer:
area after 8 years is 2156km²
Step-by-step explanation:
Area of forest=4900 km²
decrease in area in 1 year=4900km² × 7%
decrease in area in 1 year= 343km²
decrease area in 8 years=343km² × 8
=2744km²
Remaining area= (4900-2744)km²
=2156km²
Note:If you have any question about it please ask.
<em>*Distribute*</em>
3x+6+2x-8=x-3x-9
<em>*Combine like terms*</em>
5x-2=-2x-9
<em>*Add 2x to both sides*</em>
7x-2=-9
<em>*Add 2 to both sides*</em>
7x=-7
<em>*Divide both sides by 7*</em>
x=-1
Hope this helps!!
