In one month a store had $1,222 in sales but expenses were $2,345. how much money did the store lose in that month?

Profit is the difference between revenue (sales) and expenses.

... profit = $1,222 - 2,345 = -$1,123

When profit is negative, it is called a loss.

The store lost $1,123 that month.

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
