Answer:

Option B.

Step-by-step explanation:

In a circuit shown in the figure two diodes are attached in which arrow shows the direction of current allowed by the diodes.

When key S1 is closed current flows from electric source to S1 then bulb. Afterwards if key S3 is closed current will pass through S3 and diode. Therefore to light the bulb circuit will be a closed circuit if S1 and S3 both are closed.

Therefore option B. is the correct answer.

Hello may i please have help with this question
Pani-rosa [81]

Answer:

x=√139-3, x=-√139-3

Step-by-step explanation:

to complete the square, you first move the constant to the other side of the equation-its already done for you!

now, you find the perfect square trinomial. You divide the b value by 2, then square it: 6/2=3, 3^2=9.

What you do to one side has to be done with the other.

x^2+6x+9=130+9

now you can factor the square:

(x+3)^2=139

squareroot both sides:

x+3=√139

x+3=-√139

now subtract both sides by 3

x=√139-3

x=-√139-3
