Answer:
contrapositive
Step-by-step explanation:
The <u>converse</u> statement would be ...
b ⇒ a
The <u>contrapositive</u> swaps the parts and negates them both:
¬b ⇒ ¬a . . . . . matches your given statement
The <u>inverse</u> negates both parts:
¬a ⇒ ¬b
A <u>contradiction</u> arises when the implication is false: a is true and b is false.
Each neighbor will get 1/2 of the cherry pie and 1/3 of the apple pie.

<u>Let us assume that:</u>

We can also write it as:

Squaring both sides, we get:


By splitting the middle term:



<u>Therefore:</u>


<u>But x cannot be negative. </u>

Therefore, the value of the expression is 3.

Given:

We can also write it as:






This pattern will continue.
