P=x+38
add all individual sides together (is also the perimeter):
p=(x+3)+(x-5)+x+(x-2)+(x-4)+(x-1)+(x-1)
=7x-10
set both p equal:
x+38=7x-10
38=6x-10
48=6x
8=x
then insert x=8 in all the side/perimeter equations:
p=x+38=8+38=46
sides:
x=8
x-2=8-2=6
x-1=8-1=7
x-4=8-4=4
x-5=8-5=3
x+3=8+3=11
In order to determine the expression that should be multiplied to n^2 to get 5n^3, divide 5n^3 by n^2. First for the numerical coefficient, 5 divide 1 is 5. For the variable n, n^3/n^2 is n. Thus, the term that should be multiplied to n^2 is 5n.
Answer: intercept is 2/5 slope is (0,9)
a.) w = 0
Old factory: 
Plug in 0
When a number has an exponent of 0, the number becomes 1
p(0) = 238(1)
p(0) = 238
New factory: w = 0, p(0) or y = 190 (0,190)
238 - 190 = 48
During Week 0, 48 more specialty items were produced at the old factory than at the new factory.
Sorry I don't know how to do b or c
