Conditional Statement: if p then q The converse form of a conditional statement is when: O p and q are switched, and both negate
nordsb [41]
<h3>2 Answers: </h3>

B)  p and the q are switched

C) Neither p or q is negated

========================================================

Explanation:

The original conditional "if P, then Q" has P and Q swap places to form the converse. So the converse would be "if Q, then P". We don't negate P, and we don't negate Q either.

Here is the full list

  • Original = If P, then Q
  • Converse = If Q, then P
  • Inverse = If not P, then not Q
  • Contrapositive = If not Q, then not P

Side notes:

  • The original and contrapositive are equivalent in truth value.
  • The converse and inverse are equivalent in truth value.

Venus and Serena measured a tennis court and found that it was 42ft longer than it was wide and had a perimeter of 228ft. What w
mr_godi [17]

Answer:

length = 78 feet

width = 36 feet

Step-by-step explanation:

Using one variable and an expression, you can set up an equation equal to the perimeter to find the measure of each side:

width = 'w'

length = '42ft longer than it was wide' = w + 42

The general formula for the perimeter of a rectangle:

P = 2w + 2l

Plugging in the given values and variables:

228 = 2w + 2(w + 42)

Distribute: 228 = 2w + 2w + 84

Combine like terms:  144 = 4w

Divide and solve:  36 = w

w = 36 ft

l = 36 + 42 = 78 ft
