No they have the number 20. And what we need to integrate cost two weeks by cause ex players cyan X holes with. Now before integrating let us right cause to exit causes square because Squad X minus Science Quebec's by cause X Place Synnex hold squared DX. Now they suggested A square men's baseball which is A plus B. Cossacks Place Synnex into A minus B. Cossacks minus Science by cause X place sinus whole square so one of the back it will begins allowed. Oh basically we have to integrate course X minus Synnex by Cossacks plus Synnex Dx. Now if you take cause explosive Synnex as if you substitute cause sex. Place sign X equal to why? So we'll be having minus sign next after differentiation. Mind sign, explorers, car, sex the X equal to Dy. So this is completely dy So the question becomes one by why they were integration so log modify policy and why is scientific discourse, sex or concepts plus Synnex because sex place sign explicit so they shouldn't be dancing for for the number 20. Thank you
