Answer:
the answer is B
Step-by-step explanation:
when you take the first answer and subtract the second answer from it you get a negitive number of -1.1080325x10+28
A= {a,b,c,d} B = { b,d,c,f} find AUB, A∩B, n(A), n(B), n(AUB), n(A∩B)
Ludmilka [50]
<u>Given</u><u> info</u><u>:</u>
A = { a,b,c,d }
B = {b,d,c,f}
Find the following :
1) AUB
2)AnB
3) n(A)
4) n(B)
5) n(AUB)
6) n(AnB)
<u>Solution :-</u>
Given sets are A = { a,b,c,d }
⇛ Number of elements in A = 4
⇛ n(A) = 4
B = {b,d,c,f}
⇛ Number be f elements in B = 4
⇛ n(B) = 4
AUB
⇛ {a,b,c,d} U { b,d,c,f}
⇛ {a,b,c,d,f}
AUB = {a,b,c,d,f}
⇛ Number of elements in AUB = 5
⇛ n(AUB) = 5
and
AnB = {a,b,c,d} n { b,d,c,f}
⇛ AnB = { b,c,d}
⇛ Number of elements in AnB = 2
⇛ n(AnB) = 2
<u>Answer</u><u>:</u><u>-</u>
1) AUB = {a,b,c,d,f}
2)AnB = { b,c,d}
3) n(A) = 4
4) n(B) = 4
5) n(AUB) = 5
6) n(AnB) = 3
<span>Lets x is the number
A number multiplied by -9: -9x
</span><span>sum of 14 and four times the number: 14 +4x
</span><span>A number multiplied by -9 subtracted from the sum of 14 and four times the number

(14 +4x) - 9x
Hello! To answer this question, all you have to do is subtract both numbers from each other. 14.6 - 5.2 is 9.4. The numbers are 9.4 units away from each other on a number line. An expression that would represent a distance between them are 14.6 - 5.2 = x. Just make the negative numbers positive to make it easier to solve.
To get the answer, you subtract the time she spent playing with her dog (5 minutes) from 15. 15-5=10. then you subtract the time she rode her bike (4 minutes). 10-4=6. since there are 6 minutes left, she spent 6 minutes catching bugs
