Okay. So since the since these two mattresses are petitioned conform of Lee So we can just direct used the metrics modification to find out a result. And the music case I means the identity a matrix and we omit the dimension because yes, I said it before They are petitioning conform obl e So we have the first injury. Where have I times a prized zero times. See Nephila second engine. We have items be past the old times d and we have e times A plus I can see in the e times pre processed items at past items D so you can simplify this? We have a e times a process e he times beep rosti. So this is the result to this problem?
