Step-by-step explanation:

(also why is your pfp Rikka dressed as Zero two? Thats so funny bro)

if its supposed to be squared then the answer is 221

if it is not supposed to be squared then the answer is 26

Step-by-step explanation:

if that is 5x^2 then it would be 5x3 which equal 15 then we would just square it which would be 225 and subtract 4 so if it is squared then the answer is 221

if it is not squared then it would be 5x3=15 15x2=30 30-4=26

hope this helps (:

your answer would be 10x - 1
