Answer:
41.2 miles per hour
Step-by-step explanation:
To find the miles per hour you need to find how much they travel each hour. To do this divide 412 by 10. When doing this you get 41.2 miles per hour
Answer:
subtract 8x from both sides
Step-by-step explanation:
this is the first step
Answer:
Part A:

Part B:
The closure property describes cases when mathematical operations are CLOSED. It means that if you apply certain mathematical operations in a polynomial it will still be a polynomial. Polynomials are closed for sum, subtraction, and multiplication.
It means:
But when it is about division:
<u>Example of subtraction of polynomials:</u>
<u />
<u />
<u />
<u />
Step-by-step explanation:
<u>First, it is very important to define what is a polynomial in standard form: </u>
It is when the terms are ordered from the highest degree to the lowest degree.
Therefore I can give:

but,
is not in standard form.
For this question, I can simply give the answer:
and it is correct.
But I will create a fifth-degree polynomial using this formula

Also, note that

For 


Sorry but I will not type every step for each value of 
The first one is enough.
For 

Doing that for
values:

Answer:
1 or 9.
Step-by-step explanation:
A coefficient is "a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4xy)".
So, in this case, the coefficient of 9x would be 9.
The coefficient of x^2 would be 1.
Hope this helps!
103^2-102^2
The property that applies here is a^2-b^2 = (a+b)(a-b)
so the answer is 103^2-102^2=(102+103)*(103-102)= numerically it is 205( as 103+102 = 205 and 103-102 = 1.....so 205*1 = 205)
The thing is that usually the factorization ends at (102+103)(102-103) ......
