Part B Directions: Write the written form of the following expressions given in symbolic form. After you find the symbolic form, then simplify each expression.

9. 4(3x + 2) – 9
10. √144 – (62 –x)
11. (28 ÷ 4) – (x + 7)
12. x3 – 4y - (6 + 2)
13. (64 ÷ 8) – (x • 6)
14. 72 (4 - 15x)
15. 4(√144 + 93)–y
16. 54 + 7y – (8 + 9x)

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true
