Answer: 5/x3-1/x2+8/x-40 is not polynomial. The rest are polynomial.
Step-by-step explanation:
Polynomials cannot have a number divided by a variable so 5/x3-1/x2+8/x-40 can't be a polynomial.
First we need to isolate the variable so we add 15 to both sides which is
w/4=43 then we need to multiply by 4 to both sides so its 4w=172
then divide by 4 which is 43 so the answer is w=43
