Answer:
<u>x</u><u> </u><u>is</u><u> </u><u>2</u><u> </u><u>and</u><u> </u><u>-</u><u>8</u>
Step-by-step explanation:
general equation
sum is 6, product is -16
for completing squares,
first divide the sum by 2:
add the square of the result on (x² + 6x) and subtract it from the product:
take square root:
x is either: 5-3 or -5-3
Answer:
14
Step-by-step explanation:
6+3x=27
-6 -6
3x=21
/3 /3
x=7
2x7=14
Hello there.
In this problem, we can use our intuition of logic, but I will show a proof of the result in a truth table later. Then, let's get started!
Given:
→ Amelia finishes the homework (sentence H, can be True or False)
→ Amelia goes to the park (P, true or false)
Then, we have: If H, then P. Logically:
H ⇒ P
Then we can think: <em>everytime</em> she does the homework, she goes to the park. Therefore, if she did not go to the park, she will not have finished the homework (It is an equivalent sentence).
<em>Alternative 1</em>.
==========
Now, let's prove that (H ⇒P) is equivalent to (¬P ⇒ ¬H), via the truth table:
H P ¬H ¬P (H ⇒ P) (¬P ⇒ ¬H)
T T F F T T
T F F T F F
F T T F T T
F F T T T T
As we can see, the results are identical, therefore, the sentences are indeed equivalent.
I hope it hepls :)
