Perimeter

4x-7 plus 4x-7 plus 10x^2 + 4x - 2 plus 10x^2 + 4x -2.

8x - 14 plus 20x^2 + 8x - 4

(x + 36) (x+10)

x = {36, 7}

gotta go, so I cannot do the rest. I hope that helps a bit.

Just add up the lengths of the four sides, and you have the perimeter.

The perimeter is:
(4x-7)*2 + (10x^2+4x-2)*2 =
8x-14 + 20x^2+8x-4 =
20x^2 + 16x - 18

Use Ohm’s law to find the resistance of the light bulb if you had a 20 volt battery and 0.57 amps of current. Show your work for

aleksley [76]

For this case we have the following equation:
V = I * R
Where,
V: voltage
I: current
R: resistance
By clearing R we have:
R = V / I
Substituting the values:
R = (20) / (0.57)
R = 35.09 Ohms
Answer:
The resistance of the light bulb is:
R = 35.09 Ohms
