4x = -12
First, divide both sides by 4. / Your problem should look like:
Second, since 4 goes into 3 to get 12, simplify it by 3. / Your problem should look like:

Answer:
x = -3
Answer:
volume
Explanation:
things expand when heat is applied taking up more space hence volume
P1/V1=P2/V2
1/22.4=4/x
X=4 multiple by 22.4
V2=89.6L
Answer:+3
Explanation: You have to find the oxidation number of N which is +3.
Answer:
Explanation:
<em>Waves are actually energy passing through the water, causing it to move in a circular motion. ... This phenomenon is a result of the wave's orbital motion being disturbed by the seafloor.</em>
<em />
<em>The direction a wave propagates is perpendicular to the direction it oscillates for transverse waves. A wave does not move mass in the direction of propagation; it transfers energy.</em>
