Answer:
Step-by-step explanation:
Correct option is D)
Given (3q+7p
2
−2r
3
+4)−(4p
2
−2q+7r
3
−3)
According to the rules of subtraction of algebraic equation, we have negative sign will
Becomes positive and so we have to keep the big numerical sign.
Now arrange the variables in rows we get
(3q+7p
2
−2r
3
+4)−(4p
2
−2q+7r
3
−3)=(3p
2
+5q−9r
3
+7)
Answer: choice C
Step-by-step explanation:
The union of events A and B, denoted ∪ , is the collection of all outcomes that are elements of one or the other of the sets A and B, or of both of them. It corresponds to combining descriptions of the two events using the word “or.”
**keep in mind that we don’t write numbers more than once in these sets(choiceB)
so the answer would be
{3,4,5,6,7,8,9}
