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:
Step-by-step explanation:
The first composite shape is a combination of a rectangular prism and a pyramid. To find the volume of the entire shape you find the volume of each individual shape and add them together. The second figure consists of a cylinder and a hemisphere.
Answer:
AHH! Geometry!
Thanks!
The arc has a length of 1/3
Step-by-step explanation:
So you first start off with this:
This is because a circle is 360 degrees, and we are talking about a 20 degree arc.
Simplifying, we get 
So then, you multiply the circumference with this "factor"
Hope this helps!

Start by finding an equation with what is given in the question
y=0.1x+25
Sub in 54.99 for y and solve for x
54.99=0.1x=25
54.99-25=0.1x
29.99=0.1x
29.99/0.1=x
x=299.9 miles or less than 300 miles
Therefore Yolanda (what kind of name is that?!) must drive less than 300 miles in order to get to her budget.
hope this helps!
