Answer:
2x+2y ≤ 64
x=2y+2
Step-by-step explanation:
x = length
y = width
the length is 2 more than twice the width or 2 more than twice y
x = 2+2y
the perimeter of the garden = 2 times the length + 2 times the width
she have 64ft of wire so the perimeter should be equal or less than 64 ft
64 ≥ 2x + 2y

Answer:
Step-by-step explanation:
Let d represent the number of dimes Molly has. Then she has 18-d nickels, and the total value (in cents) of her coins is ...
5(18 -d) +10d = 105
5d +90 = 105 . . . . . . simplify
5d = 15 . . . . . . . . . . . subtract 90
d = 3 . . . . . . . . divide by 5; number of dimes
18-d = 15 . . . . . number of nickels
Molly has 3 dimes and 15 nickels.
Answer:
I think the oil pollutes the groundwater
Step-by-step explanation:
My six grade science teacher once taught us something about this, but that was a year ago so I might be wrong, but I'm pretty sure that the oil will spread and then pollute local rivers and streams, by polluting the groundwater.
Answer:
x'-5x=0, or x''-25x=0, or x'''-125x=0
Step-by-step explanation:
The function 
is infinitely differentiable, so it satisfies a infinite number of differential equations. The required answer depends on your previous part, so I will describe a general procedure to obtain the equations.
Using rules of differentiation, we obtain that 
. Differentiate again to obtain, 
. Repeating this process, 
.
This can repeated infinitely, so it is possible to obtain a differential equation of order n. The key is to differentiate the required number of times and write the equation in terms of x.
