Hello,

x² + 5x + 6 = 0

a = 1 ; b = 5 ; c = 6

∆ = b² - 4ac = 5² - 4 × 1 × 6 = 25 - 24 = 1 > 0

2 solutions :

$x_{1} = \frac{ - b - \sqrt{\Delta} }{2a} = \frac{ - 5 - 1}{2 \times 1} = \frac{ - 6}{2} = - 3$

$x_{2} = \frac{ - b + \sqrt{\Delta} }{2a} = \frac{ - 5 + 1}{2 \times 1} = \frac{ - 4}{2} = - 2$

S = { -3 ; -2}

A microwave is the only electric device in a 120-volt circuit. If the circuit has 7.5

bogdanovich [222]

The electric power of microwave is 900 watts.

Step-by-step explanation:

Given,

Voltage in the circuit = 120 volts

Current in the circuit = 7.5 amp

Electric power of microwave = Voltage*Current

Electric power of microwave = $120*7.5$

Electric power of microwave = 900 watts

Therefore,

The electric power of microwave is 900 watts.
