Question

Let P represent The area of rectangle ABCD is 50sqin. Let Q represent the perimeter of rectangle ABCD is 30in. Let R represent The length of rectangle ABCD is twice the width

1.If rectangle ABCD is 9in long & 6in wide, what is the truth of the disjunction Qv ~P?
a.True, b.False, c.Cannot be determined

2.Suppose rectangle ABCD is 12.5in long & 4in wide. What is the truth value of the conditional P-->R?
a.True, b.False, c.Cannot be determind

-Use the law of detachment or the law of syllogism to determine a conclusion that follows from statements 1 & 2. If a valid conclusion does not follow, write no valid conclusion.

1.If a triangle is a right triangle, the it has 2 acute angles.
2.Triangle ABC is a right triangle.
a.No valid conclusion,
b.Triangle ABC does not have 2 acute angles
c.Triangle ABC is a right triangle
d.Triangle ABC has 2 acute angles

Answer 1

1. Q is true P is false. So not-P is also true. You take it from there.

2. P is true R is false. So P--->R is false.

3. c and d are true. I'd say both are valid. I'm not clear on what I'm missing, unless you made a typo.

Answer 2

no idea
