Hello,
The answer would be "2^2*3*7".
Reason:
The prime factorization of 84 is 84:
Therefore wrote in a expression would equal....
<span>2^2*3*7
2^2=4
4*3=12
12*7=84
If you need anymore help feel free to ask me!
Hope this helps!

Answer:
Step-by-step explanation:
Given that radius of the circle = 10
Using π, we need to find about which equation expresses the ratio of the circumference of the circle to the circle's diameter.
diameter of the circle = 2(radius) = 2(10)=20
circumference of the circle = 2 π r = 2 π (10) = 20 π
then ratio of the circumference of the circle to the circle's diameter is given by: 
.
Hence required equation is
Answer:
x=-6
Step-by-step explanation:
5x-x-6=6(2x+7)
4x-6=<em>6(2x+7)</em>
4x-6=<em>12x+</em><em>42</em>
-8x=48 |:(-8)
x=-6
Recall that a ⇒ b ≡ ¬a ∨ b.
• r ⇒ (p ∧ q) ≡ ¬r ∨ (p ∧ q)
In row C, q is false so p ∧ q false, and r is true so ¬r is false.
¬r ∨ (p ∧ q) ≡ false ∨ false ≡ false
• r ⇒ (p ∨ q) ≡ ¬r ∨ (p ∨ q) = p ∨ q ∨ ¬r
In each of rows A, C, and E, at least one of p or q is true, so
p ∨ q ∨ ¬r = true
• (q ∧ r) ⇒ p ≡ ¬(q ∧ r) ∨ p ≡ (¬q ∨ ¬ r) ∨ p = p ∨ ¬q ∨ ¬r
In row E, p is false and both q and r are true, so ¬q and ¬r are both false.
false ∨ false ∨ false = false
• (q ∨ r) ⇒ p ≡ ¬(q ∨ r) ∨ p ≡ (¬q ∧ ¬r) ∨ p
In row E, p is false and both q and r are true, so both ¬q and ¬r are false.
(¬q ∧ ¬r) ∨ p ≡ (false ∧ false) ∨ false ≡ false ∨ false ≡ false
