2 log(<em>x</em>) - log(<em>x</em> - 1) = log(<em>x</em> - 2)
log(<em>x</em>²) - log(<em>x</em> - 1) = log(<em>x</em> - 2)
log(<em>x</em>² / (<em>x</em> - 1)) = log(<em>x</em> - 2)
<em>x</em>² / (<em>x</em> - 1) = <em>x </em>- 2
<em>x</em>² = (<em>x</em> - 1) (<em>x</em> - 2)
<em>x</em>² = <em>x</em>² - 3<em>x</em> + 2
0 = -3<em>x</em> + 2
3<em>x</em> = 2
<em>x</em> = 2/3
But notice that 2/3 - 1 = -1/3 < 0, and log(<em>x</em> - 1) is undefined so there are no real solutions.
Answer:
Because you are looking for square inches of wrapping paper, you are looking for the surface area of the box. A three-dimensional box has a top and bottom that are the same size, a front and back that are the same size, and 2 sides that are the same size...or SA = 2(top/bottom area) + 2(front/back area) + 2(side/side area). Our equation fills in nicely like this:
SA = 2(6 * 14) + 2(6 * 8) + 2(14 * 8)
SA = 2(84) + 2(48) + 2(112)
SA = 168 + 96 + 224
SA = 488 square inches of paper to wrap the box.

Answer:
Number of shopper buy from sale [3,000shopper] = 600 (Approx.)
Step-by-step explanation:
Given:
Number of shopper in mall = 60
Number of shopper buy from sale = 12
Find:
Number of shopper buy from sale if total number number of shopper are 3,000
Computation:
Number of shopper buy from sale [3,000shopper] = 3000[Number of shopper buy from sale/Number of shopper in mall]
Number of shopper buy from sale [3,000shopper] = 3000[12 / 60]
Number of shopper buy from sale [3,000shopper] = 3000[1/5]
Number of shopper buy from sale [3,000shopper] = 600 (Approx.)
