Answer:
For
, the group is CLOSED as it a polynomial.
Step-by-step explanation:
Here, the given polynomials are:

Now, a group G is said to be <u>CLOSED UNDER SUBTRACTION</u> if,
a and b are he elements of G ⇒ (a-b) is ALSO AN ELEMENT of G
Now, here:

or, 
Also, R(x) is a POLYNOMIAL.
So, R(x) is an Element of group G.
So, the set G of polynomials.
Hence, for the polynomial
, it will be a polynomial the group is CLOSED.
Answer: the answer is 1326 ins
Step-by-step explanation:
Answer:
n = (177-45)/2
hope this helps! If so I would really appreciate brainliest
9 + 9n = 9
*subtract 9 from both sides
9n = 0
*divide both sides by 9
n = 0/9 = 0
n = 0
