Answer:
distributive property
Step-by-step explanation:
You are distributing the 8 amongst the numbers inside the parenthesis.
-9x from both sides
5x+2=-3
-2 from both sides
5x=-5
x= -1
Answer:
The new current is half the original current.
Step-by-step explanation:
Ohm's Law:
We use Ohm's law to solve this question. It states that
In which 
is the voltage difference, R is the resistence, and I is the current.
A student builds a simple circuit with a single resistor with resistance R and measures an electric potential difference ΔV across the resistor.
So
![I_{1} = \frac{\Delta_V}{R}{/tex]Then, the student replaces the resistor with a new one of resistance 2R and keeps the electric potential difference the same.Now the current will be[tex]\Delta_V = 2RI_{2}](https://tex.z-dn.net/?f=I_%7B1%7D%20%3D%20%5Cfrac%7B%5CDelta_V%7D%7BR%7D%7B%2Ftex%5D%3C%2Fp%3E%3Cp%3E%3Cstrong%3EThen%2C%20the%20student%20replaces%20the%20resistor%20with%20a%20new%20one%20of%20resistance%202R%20and%20keeps%20the%20electric%20potential%20difference%20the%20same.%3C%2Fstrong%3E%3C%2Fp%3E%3Cp%3ENow%20the%20current%20will%20be%3C%2Fp%3E%3Cp%3E%5Btex%5D%5CDelta_V%20%3D%202RI_%7B2%7D)
The new current is half the original current.
Based on the given description above, the correct answer would be the second statement. If two lengths of two sides of a triangle are 9 and 15, therefore, the length of the third side <span>must be greater than or equal to 6 and at most 24. Hope this answer helps. </span>
