Answer:
<h2>x = 1</h2>
Step-by-step explanation:

Expand the terms in the bracket and simplify
That's

<u>Add 2x to both sides of the equation</u>

<u>Subtract 3 from both sides of the equation</u>

<u>Divide both sides by 5</u>

We have the final answer as
<h3>x = 1</h3>
Hope this helps you
i believe 2/21 is the answer, correct if im wrong
Answer:
1.
- Heat capacity is defined as the total amount of heat required to increase the temperature of a substance in 1°C.
- Specific heat is defined as the total amount of heat required to increase the temperature of a substance in 1°C per unit mass. Hence this property depends of the mass of the substance.
- Latent heat is the amount of energy absorbed or released by a substance in a phase change (physical change) without a change in temperature.
2.
- Degrees of freedom is the number of parameters that define the configuration of a system. For example, in a system with we want to know about the dynamic in the three dimension x,y,z and also about the rotation around a fixed axe we have four degrees of freedom.
- Equipartition theorem relates the temperature of a system with the average energy of the system (this average is taken for those degrees of freedom that appears quadratically).

Answer:
<u>A) 2¹²</u>
Step-by-step explanation:
Given :
Equate the equation to y :
- 3x - y + y = 12 + y
- 12 + y = 3x
- 12 + y - 12 = 3x - 12
- <u>y = 3x - 12</u>

Substituting in the expression :
