Answer:
3
Step-by-step explanation:
2x + 2y = 4
dividing both sides by 2,we get
x + y = 4,which is the same line A
so this set of equations has infinitely many solutions as they intersect each other at infinite points i.e they overlap eachother
Answer: 6. When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged.
7. The neutral electroscope becomes charged as the result of being contacted by the metal sphere. In contrast to induction, where the charged object is brought near but never contacted to the object being charged, conduction charging makes the physical connection of the charged object to the neutral object
8. Grounding is the process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size. When a charged object is grounded, the excess charge is balanced by the transfer of electrons between the charged object and a ground.

Step-by-step explanation: Do NOT copy word for word but this will give an idea
The answer is B

So,
You have to undistribute a common factor in all of the terms.
2a + 2b
There is a 2 in each term.
Undistribute.
2(a + b)
-6/5,-236/5 would be the minimum
