The correct quadratic equation;
x2+7x-2=0
Working
Assuming the frame has a uniform thickness;
Then length of mirror and frame is 3+x and width 2+x
The area of mirror and frame area;
A=L*W
8=(3+x)(2+x)
8=(6+5x+x2)
Taking 8 to the Right hand side, we have:
x2+5x-2 =0

Answer:
We need to start with 5 kg of mushrooms
Step-by-step explanation:
The total of the dried mushrooms = mushrooms * percentage of weight kept
percentage of weight kept = 1- 80% = 20 %
We want 1 kg of dried mushrooms. Substitute in what we know
1 kg = mushrooms * 20%
1 kg = mushrooms * .2
Divide each side by .2
1 /.2 = mushroom *.2 /.2
5 kg = mushrooms
We need to start with 5 kg of mushrooms
