x^2-x-72 =0
find 2 numbers when multiplied = -72 and when added = 1
the zeros are 9 and -8
I don’t know sorry but hope you get the answer
A decrease of 8.25% means the reduction factor is 100-8.25=91.75%=0.9175.
The shrinkage over 15 years is 0.9175¹⁵=0.27485 approx, so the size of the forest will be 3100×0.27485=852 sq km approx.
The slope of the line is 3/2
