Answer:
<em>12 </em>
<em> + 28 </em>
<em> - 60 r³ + 28 r² </em>
Step-by-step explanation:
a(b ± c) = ab ± ac (distributive property)

2r²(6r³ + 14r² - 30r + 14) = <em>12 </em>
<em> + 28 </em>
<em> - 60 r³ + 28 r²</em>

Answer:
180°
Step-by-step explanation:
Answer:
I don't remember the name of the law, but it states that when resistors are connected in series they put up one singular resistance. so,
Let smaller resistance be x
greater resistance is 3x
According to the question,
x+3x=12
4x=12
x=3
therefore,
resistors are of 3 ohms and 3×3=9 ohms
Answer:
100
Step-by-step explanation:
Because if 50 percent of x is 50 than x = 100
