The perimeter is 40.4m because 39.6/2.2=18 and since there are 4 sides, add 18 twice as the longer sides. 2.2 is the length of the two shorter sides so you add 18+18+2.2+2.2 to get 40.4m.
5^2
Step-by-step explanation:
You just add the exponents
-3 +5 =2
First combine like terms
5+4= 9
1/4s-2/3s= -5/12s
-5/12s= 9
S= -21.6
The given numbers are a set of points. To convert this into a linear data set, you can do data fitting. The easiest way to do this is using a software. In this case, I used MS Excel. You plot the points and set a linear trendline. The linear equation for this set of data is: y = 0.286x + 0.784
