Find the value of the power.

7^4 =

49xy +34y - 72z. determine the degree of the polynomial

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.

Anyone know? is appreciated! will mark brainliest if correct!
