Draw a Venn diagram and use the given information to fill in the number of elements for each region. n(Upper A primeA′)equals=
25, n(B)equals=32, n(Upper A primeA′union∪Upper B primeB′)equals=38, n(Aintersect∩B)equals=17
1 answer:
Answer:
see below
Step-by-step explanation:
It works reasonably well to start with A∩B = 17. (As a general rule, starting with the intersection of all regions makes it easier to sort out the rest.)
Then you can use B=32 to fill in A'B = 15. After that, you can use A'=25 to fill in A'B' = 10.
At this point, you can use (A∩B)' = 38 to fill in AB'=13.

Answer:
Since the perimeter is 56 inches we can solve for the lenght with this equation:
And solving for the length we got:
So then the lenght = 16 inhes and the width of 12 inches
Step-by-step explanation:
For a rectangle of width 12 inches and lenght y inches we know that the perimeter is given by:
Since the perimeter is 56 inches we can solve for the lenght with this equation:
And solving for the length we got:
So then the lenght = 16 inhes and the width of 12 inches
