Question

1)cab-4cad-cbd from 3abc+5bcd-cda
2)how much less 2a square is than 3a square-6
3)how much smaller is 15x-18y+19z than 22x-20y-13z+26

Answer 1

Answer:

given down

Step-by-step explanation:

1...(3abc+5bcd-cda)-(cab-4cad-cbd)

=3abc+5bcd-cda-cab+4cad+cbd

=2abc+6bcd+3cda

SO,answer is 2abc+6bcd+3cda

2...(3a^2-6)-2a^2

=3a^2-2a^2-6

=a^2-6

SO,2a^2is smaller by a^2-6

3...(22x-20y-13z+26)-(15x-18y+19z)

=22x-20y-13z+26-15x+18y-19z

=(22x-15x)+(-20y+18y)+(-13z+19z)+26

=7x-2y+6z+26

SO,15x-18y+19z is smaller by 7x-2y+6z+26
