Answer:
This equation has two solutions.
1 solution is: x - 1
Solution #2 is : x - 7
Step-by-step explanation:
1. Move the constant to the left. We end up with x^2 - 8x +7 = 0
2. Rewrite the expression: x^2 - x - 7x + 7 = 0
3. Factor the expressions: x * (x-1) -7(x-1) = 0
4. Separate into possible cases : (x-1) * (x-7) = 0
5. Solve the equation(s): x-1 = 0
x-7 = 0
6. Possible solutions are as follows: x-1 OR x-7
The current in the circuit will be equal to (10 - 3j)/(4 + j) when the voltage is 10 - 3j and impedance is 4 + j.
<h3>What is Electrical energy?</h3>
When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible.
When two charge are in opposition to one another, they repel one another. The term "neutral" refers to an object has no net charge.
As per the given information in the question,
Voltage, E = 10 - 3j
Impedance, Z = 4 + j
Then, the value of current will be,
E = IZ
I = E/Z
I = (10 - 3j)/(4 + j)

Answer:
14,104 centimeters
Step-by-step explanation:
This equation is asking for the total height of the wall in centimeters. Given that it gives you both sections of the wall, we will want to add them together to find our total.
5,224 + 8,880 = 14,104
