Question

subtract the sum of 9+xy-x²and x²+1 from the sum of x²+xy-2 and 3xy+7​

Answer 1

Answer:

I'n short human made resources are resources that are made by human like T.V tv is resource of entertainment

Answer 2

9+xy-xsquare (coz i am using pc)+xsquare+1                       (note that s=power 2)

=9+xy-xs+xs+1

=9+xy-2xs+1

=9+1+xy-2xs

=10+xy-2xs

hence,first question answer is 10+xy-2xs

sum of xs+xy-2+3xy+7

=xs+xy-2+7+3xy

=xs+xy+5+3xy

=xs+xy+3xy+5

=xs+4xy+5

 hence,                xs+4xy+5

                          -2xs+xy+10

                       --------------------

                          -1xs +5xy +15

hey mate here is your answer it took so much time please mark me as brainliest answer is right or wrong??
