I assumed I had to multiply 2 times each factor 2(VI). I got it now... thank you so much for your help!

the answer is just not coming out: I plugged in Ppeak=2(Vrms*Irms) which is 1180=2(120)*2Irms 1180/240=2Irms Irms=2.458 am I not getting something? or is it a number thing?

thats the part I don't understand, how to combine the two equations to get the relationship between the two, are they equal because power is conserved?

I found a value for R with P=V^2/R and tried plugging that into P=I^2R, then I took that I multiplied by .707
