Answer:

  • 10.5cm,20.8cm,23.3cm — yes
  • 6cm, 22.9cm,20.1cm — no

What is 2xy-3yz+5+2yz-xy
melomori [17]

To simplify this expression, we are going to combine like terms.


First, we can see that we have two terms with the variables xy being multiplied together, 2xy and -xy. Together, these add to xy, so our expression is now:

xy - 3yz + 5 + 2yz


We also have two terms with yz, -3yz and 2yz. Together, these add to -yz, so our expression is now:

xy - yz + 5


Our final expression is xy - yz + 5.
