Distribute the -1/2 to both x and 12
-1/2(x) = -1/2x
-1/2(12) = -6
12 - (-1/2x) - 6
Simplify: Note, two negatives = one positive
12 + 1/2x - 6
Simplify: combine common numbers together
12 - 6 + 1/2x
6 + 1/2x
1/2x + 6 is your equivalent expression
hope this helps

Answer:
(p ∧ q)’ ≡ p’ ∨ q’
Step-by-step explanation:
First, p and q have just four (4) possibilities, p∧q is true (t) when p and q are both t.
p ∧ q
t t t
t f f
f f t
f f f
next step is getting the opposite
(p∧q)'
<em>f</em>
<em> t</em>
<em> t</em>
<em> t</em>
Then we get p' V q', V is true (t) when the first or the second is true.
p' V q'
f <em>f</em> f
f <em>t</em> t
t <em>t</em> f
t <em>t</em> t
Let's compare them, ≡ is true if the first is equal to the second one.
(p∧q)' ≡ (p' V q')
<em>f f </em>
<em> t t</em>
<em> t t</em>
<em> t t</em>
Both are true, so
(p ∧ q)’ ≡ p’ ∨ q’
Answer:
6a^8/3a^4= (6/3)= 2
a^8/a^4= a^4
2a^4
(6/3)(a^8/a^4)= 2a^4
(6/3)(a^(8-4))= 2a^4
