Answer:
w=16, L=20
Step-by-step explanation:Length(L)=w+4
P=72
P=2L+2w
P=2(w+4)+ 2w
P=2w+8+2w
72=4w+8
4w=72-8
4w=64(/4)
w=16
L=16+4=20
Verification: 16+16+20+20=72
32+40=72
72=72 (T)

Answer: check explanation
Step-by-step explanation:
Multiply both sides of equation by x(x+a)
This will get rid of those nasty fractions...cuz who likes them?
Anyways,
Now you should I think get
x(x+a)+a(ax)=a
I am pretty positive that you just distribute and solve.
You may have to factor and have to put everything as an equation set to equal=0
you try it and experiment. Sometimes you just have to try to think algebraically and creatively. Don’t get frustrated just work with it. Good luck!

Answer:
quadratic
Step-by-step explanation:
The fact that function values are decreasing, then increasing tells you the function cannot be modeled by a linear or exponential function.
A quadratic model is most appropriate.
