If possible, come to UWW campus, McGraw Hall room 115 at any time between 5:30 PM and 10 PM to take your first exam. This room is a special computer lab which can accommodate 20 students at once, first-come-first-serve. Students in excess of 20 must wait. I will estimate that it will take the average student 45-60 minutes to take EXAM #1. If this time interval is not possible for you, contact Prof McFarland. Since Prof McFarland has only one PC, however, an office visit may require you to wait or return at a time when his only PC is free; thus, you should call first to use this option.

Each of your 4 tests will have the appearance below.
Actual tests will have 25-35 questions; this sample has 10.
You will click on the appropriate answer for each question.
In an actual test, you will send these answers to your Professor: see bottom of test
Links to other web pages (in this sample test) will NOT be on actual tests.

Enter student I.D. above

 [1] Which of the following illustrates the associative property of multiplication? (a) 2(x + y) = 2x + 2y (b) (x + 1)(x - 1) = (x - 1)(x + 1) (c) a(bc) = (ab)c (d) x.1 = x (e) x + 0 = x
 [2] Find the solution set of the equation: |2x - 3| = 1 (a) {1} (b) {2,1} (c) {0,1} (d) {-2} (e) none of the above
 [3] What is the solution for the inequality "7 - 3x < 19" ? (a) x > -4 (b) x < -4 (c) x > 4 (d) x < 4 (e) none of the above
 [4] Let x represent the length (in feet) of one side of a square. Translate into mathematical symbols: "If two opposite sides of a square are each increased by 6 feet, and the other two sides are each reduced by 5 feet, the resulting rectangle has the same area as the square." (a) x2 - 30 = 0 (b) (x + 6)(x - 5) = x2 (c) (x + 6)(x - 5) = 30 (d) x2 + 6 - 5 = x2 (e) none of the above

[6]
 Enter the value of x which solves the equation: x3 - x - 55 = 3
[7] Enter the coefficient and power of x which makes the equation true:

 54x2 ( 3x-2)-3 = x See Rules for Exponents?
[8] Enter the two factors which make the equation true:
