The perimeter of a rectangle is given by:
P = 2W + 2L
Where,
W: width
L: long
Substituting the values we have to:
P = 2 * (33 + 2 * (3)) + 2 * (39 + 2 * (3))
P = 168 feet
Answer:
joe needs to enclose the garden and path 168 feet of fencing material
a + m = 30
a = m - 8
(m - 8) + m = 30
2m - 8 = 30
2m = 30 + 8
2m = 38
m = 38/2
m = 19
a = m - 8
a = 19 - 8
a = 11
so Amy has $11 and Maria has $ 19
I assume you mean 
, and not 
, since this doesn't satisfy the ODE.
Assume a second solution of the form 
, where 
is a function of 
. Then
Substituting into the ODE gives
where we omit the second term because it's already accounted for by 
.
