Answer:
a) (C∪P)-B
b) (U-B)∩(U-C)∩(U-P)
c) B∩C∩P
d) P-(B∪C)
e) (B∪C)-P
Step-by-step explanation:
We can use three operations between sets:
- Union: X∪Y is the set of elements that belong to X or belong to Y
- Intersection: X∩Y is the set of elements that belong to X and belong to Y
- Difference: X-Y is the set of elements that belong to X and NOT belong to Y.
The sets we can use in each part are U,B,C and P
a) A customer that likes corn dogs belongs to C, and a customer that likes pizza belongs to P, then a customer who likes corn dogs or pizza belongs to C∪P. The customers from this problem do not like burgers, so they don't belong to B. From this, the required set is (C∪P)-B
b) The customers do not like burgers, so they do not belong to B. However, they visit the restaurant so they belong to U. Thus, the customers belong to U-B. Similarly, because the customers do not like corn dogs and do not like pizza, they belong to U-C and U-P. Then the set of customers is (U-B)∩(U-C)∩(U-P).
c) The customers are in B, C and P so they belong to B∩C∩P.
d) The customers belong to P (they like pizza) but they do not belong to (B∪C), thus they belong to P-(B∪C)
e) The customers belong to B∪C but they do not belong to P, so the required set is (B∪C)-P.

40×(-2) = -80 ........
The answer is expressions D, E, and G.
In algebra, a ‘term’ usually means the different parts of an expression that are separated by + and - signs.
Options A and B only have 1 term, an x or y³, so these are incorrect.
Option C has 1 term as well, ‘xyz’, because they are all multiplied together which makes it one term.
D and E both have 3 terms each, but F has 4 unique terms so this is incorrect also.
G has 3 unique terms, x³, x^4, and 7x, so this is correct.
When H is expanded, you will end up with more than 3 unique terms, so this is incorrect.
I hope this helps!
