(4g^2 + 4g + 8) - (g + 3)

Geometry ? i don't know how to do any of these.

7x+8y=-18, 4x-9y=-3 solve the system of equations

Select the correct answer from each drop-down menu. rewrite the formula to find voltage. the formula for electrical power (p, in watts) is where v is the voltage in volts and r is the resistance in ohms. for a particular brand of water heater, r is 32 ohms and p is 0.5 watts. the formula to find v is , and the voltage at which the heater operates is volts.
