Answer:
-26
Step-by-step explanation:
so, the absolute value of 3 and 11 together is 14.
14-(15+3+2)2
14-(20)2
14-40
-26
Step-by-step explanation:
(-7)+(-6)+(-1)=-14
(-14)-3=-11
-11÷7=-1.5714285714286 or -2 if you round too the tenths place
It is T because the sign in front of 50 means to square the number after it. So 50/2=25.
Answer:
<em>The voltage at the middle source is</em> 
Step-by-step explanation:
<u>Voltage Sources in Series</u>
When two or more voltage sources are connected in series, the total voltage is the sum of the individual voltages of each source.
The figure shown has three voltage sources of values:



The sum of these voltages is:

Operating:

We know the total voltage is
, thus:

Equating the real parts and the imaginary parts independently:
4+a=6
1+b=-3
Solving each equation:
a = 2
b = -4
The voltage at the middle source is 
bro doesnt it say the correct answer right there??
