Answer: All of the operations that you have listed will produce a polynomial. Therefore, they are all closed for polynomials. (Did you have a typo?)
When we say an operation is closed for a particular problem, we mean that the resulting answer is of the same type as at the beginning.
In these cases, we are starting with polynomials in each problem. After performing the operations, we still have polynomials. Therefore, they are all closed.
Answer:
128 miles
Step-by-step explanation:
320/5=x/2 640=5x x=128
The answer is k-2/9 because it says that k is decreased which means u substrate and then it's says the quotient of 2 and 9 which means that u divide so then u get 2/9
Answer:
44.4
Step-by-step explanation:
yes
Arc PQR has the central angle (360 - [150+73]), or 223. The circumference of this circle is C = pi*2*r, or C = pi*2(6.48 in) = 40.72 in. The arc length in question is a fraction of that, namely:
223
----- * 40.72 in = 25.22 in (answer)
360
