for throwing Numa right here. So we're going to find frizzy in equation Z Square minus 25 is equal to 39. So the first thing we're going to do is at 25 1 both sides and then we get Z square is equal to four one six. So we know we're going to square root both sides to find for the let me get Z is equal to plus minus eight.
