Members of a club are selling calendars as a fundraiser. The club pays $100 for a box of wall and desk calendars. They sell wall calendars for $12 and desk calendars for $8.Write an algebraic expression to model the club's profit from selling w wall calendars and d desk calendars.

12w + 8d = 100

Step-by-step explanation:

Given:

Price of wall calendars = $12

Price of desk calendars = $8

Total amount pay = $100

Computation:

w = wall calendars

d = desk calendars

So,

Price of wall calendars(w) + Price of desk calendars(d) = Total amount

12w + 8d = 100

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
