Thanks for the help

1. Factor: 3x- - 2x - 8 The two factors are in the general form: (d x + e)(x + f). What is dx te ? (A) 2x - 9 (B) 3x + 3 (C) 3x + 9 (D) 3x +4 (E) none of these 2. The sum of the two digits of a positive integer is 12. When the digits were reversed, the new number was 54 greater than the original. What is the product of the digits of the original number minus the original number? (Hint: First solve for the original number.) (A) - 66 (B) -16 (C) -12 (D) - 40 (E) none of these 3. Factor: 64al - m'n (A) (32a -m3/2n5)2 (B) (4a*+mn )(16a*-4a*mn*-man8) (C) (8at-mn*)3 (D) (4a*-mn)(16a +4a*mn*+man) (E) none of these 4. Solve for x, y, z: (4x - y =4} {y - 5z=-12} {5x + z= 19} Then evaluate: x + y + z = (A) 161 3 (B) - 43 (C) 15 (D) 57 (E) none of these 5. Write 4.545 as a fraction of integers 4541 909 450 4545 (A) 999 (B) 200 (C) 99 (D) 1000 (E) none of these6. Expand: (al/2 + 61/2)2 (A) al/4+6 1/4 (B)a+(ab)1/2+b (C) atb (D) a+2al/261/2+b (E) none of these 7. Which inequality is graphed on the number line at right ? D = {Integers; 6 -5 4 -3 -2 -1 0 1 2 3 4 5 6 (A) x2 - 3x +5>0 (B) ( x + 3) ( x - 5)20 (C) x2 + 2x - 1520 (D) - 3
