Answer:
1.91 Ohms
Step-by-step explanation:
It is given that the resistance of the conductor is 3.18 Ohms/1000 feet.
It means that the resistance of the 1000-foot conductor is 3.18 Ohms.
So, the resistance of the 600-foot #12 (solid) aluminium conductor is 
= 6 × 0.318
= 1.908
= 1.91 Ohms (rounded to two decimal places)
Answer:
Step-by-step explanation:
2x=6-2y
x=3-y
2y=6-2x
y=3-x
Lets write this out:-
z² + z + 4z³ + 4z²
z² will become 1z² because when ever there is a varaible, and before it there is NO coefficient the coefficient automatically becomes 1. Same is with z. z will be come 1z.
Lets write it out again:-
1z² + 1z + 4z³ + 4z²
Combine like terms:-
1z² + 1z + 4z³ + 4z²
(1 + 4)z² = 5z²
1z + 5z² + 4z³
So, when combining like terms in z² + z + 4z³ + 4z² the answer is
1z + 5z² + 4z³.
Hope I helped ya!! xD
