Answer:
A∩B={
}
B is a proper subset of A:
B⊂A
Step-by-step explanation:
A∩B means the intersection of the set A and the set B. In other words, is the set of elements contained in these both sets.
Given the set A and the set B:
{
}
{}
You can indentify that the numbers common in both sets are: 25,45 and 65.
Therefore you get:
A∩B={}
Since all elements of B are in A, and A contains elements that are not in B, then B is a proper subset of A:
B⊂A

Answer:
6.75 miles per half hour
Step-by-step explanation:
Answer:
Coefficients are 2, 5, -1. (Coefficients are the numbers before the x)
Constant is 3 (constant is the number without any x)
2x^5+0x^4+5x^3+0x^2-x+3
You start with the biggest and end with the smallest, if anything isnt present int he original equation (for example x^4 in this case) put it in with a zero before it.
