s = 2(lw + lh + wh)
Divide each side by 2 : s/2 = lw + lh + wh
Subtract 'lh' from each side: s/2 - lh = lw + wh
Combine the 'w' terms: s/2 - lh = w(l + h)
Divide each side by (l + h): (s/2 - lh) / (l + h) = w
Answer:. C is not a function.
Step-by-step explanation: If there is more than one y-value for each x-value, it can't be a function. The elipse has two y-values for each x.
3/5x+22=28 (Simplify, get all the whole numbers on one side)
-22 -22
5(3/5x)=(6)5 (Get rid of the fraction by multiplying everything by 5)
3x=30 (Get the variable by itself, divide by 3)
x=10
6/5 because how do you convert a percentage to a decimal? First you move the decimal points over by two, so you start off with 120 and end with 1.20. There are many ways you can go from here. If you have a graphing calculator like i do, then you type in 1.20 hit the "math" button, hit enter and a fraction already in its simplest form is given. I hope this helps, have a great day.
