Answer: =x2+7x+5
Step-by-step explanation:
−3x2+2x−4+4x2+5x+9
=−3x2+2x+−4+4x2+5x+9
Combine Like Terms:
=−3x2+2x+−4+4x2+5x+9
=(−3x2+4x2)+(2x+5x)+(−4+9)
=x2+7x+5
Answer:
=x2+7x+5

Answer:</h2>

<h2>
Step-by-step explanation:</h2>
If resistors are in series, so the current
is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance of series combination and the four resistors as follows:

is the total resistance
. Moreover:

Therefore:

Answer:
3 1/4
Step-by-step explanation:
3 5/8 is too long
3 is too short so is 3 1/8
