B. Exercises question 20-23 Draw a Venn diagram illustrating the relationship of each pair of sets. State a probable universal set in each case.
20. C = {Bible, English, math},
21. L = {Kansas, Kentucky},
D = {history, science}
M = {Alabama, Arizona, Arkansas, Kansas
22. A = {-1, 2, 4, 9), B = {1, 2, 4,6}
23. M = {2, 3, 4, 5, 6], P = {3,5)

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
