This basically is telling you what is 5% of 80.
80 × 5 = 400
400 ÷ 100 = 4
Your answer is 4 people.
Hello,
1) Verify if it is a 2 degree.
2) y=ax²+bx+c
Calulate a,b,c by Gauss's methode
a=3, b=0,c=-1
y=3x²-1
The common ratio is 5 because each number is being multiplied/divided by 5
Well you first have to find the area of the first square so do 5 times 5 which equals 25. Then you have to add 3 to 5 which is 8, so each side equals 8 meters. Next time 8 by 8 which equals 64, then do 64-25 which equals 39. Then put the change over original so do 39 divided by 25 which equals your percent of change 1.56 or 156% increase.
