Answer:
yes, 18 is a polynomial
Step-by-step explanation:
We have to show whether 18 is a polynomial or not
Polynomial is an expression involving variables and constants such that variables having non negative integer power.
Example 
etc,
Thus, yes 18 is a polynomial
as 18 can be written as 
where 
and 0 is non negative integer,
Thus, yes 18 is a polynomial as it can be written as having non negative integer power 0.
Step-by-step explanation:
log(x+2)-log(x-1)=log2
log(x+2)/(x-1)=log2
=> (x+2)=2(x-1)
=>x+2 =2x-2
=> x=4
Regular Pirce = $80.
Discount = 20%
Discount = 20% x $80 = 0.2 x 80 = $16
Sale Price = 80 - 16 = $64

Answer:
e : g = 2 : 7
Step-by-step explanation:
e/f = 3/7
e = 3f/7
f/g = 2/3
g = 3f/2
e/g = (3f/7)/(3f/2) = 2/7
