L=16
W=21
Set up a systems of equations:
x=length
y=width
xy=336
x+5=y
Use substitution to solve:
x(x+5)=336
x^2+5x=336
Solve using factoring:
x^2+5x-336=0
(x-16)(x+21)=0
x=16 and x= -21
Since length can't be negative, l=16
To find width, plug length into the first equation:
(16)y=336
y=21
So...
L=16

Answer:
48 , 96
Step-by-step explanation:
You are doubling each number
Given the arithmetic sequence is given by:
an=4-3(n-1)
writing the above into a straight line form we get:
an=4+3-3n
an=-3n+4
this a straight line equation with a negative slope, thus the domain will be:
(-∞,∞)
