Esme says the two expressions 4x - 5.2y + 6y + 7.9x - 8x and 19.9x + 11.2y are equivalent. Is she correct? Explain how you know.
Ipatiy [6.2K]

Answer:

No, she's incorrect. 4x - 5.2y + 6y + 7.9x - 8x = 3.9x + 0.8y

Step-by-step explanation:

To find out if Esme is correct, we have to group the like terms and simplify.

  • (4x+7.9x-8x) + (-5.2y+6y)
  • 3.9x+0.8y

As you can see, 3.9x + 0.8y is the correct simplified expression, thus making Esme incorrect.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

If the lengths of the sides of a square are halved, the area is the new square is..
bazaltina [42]

Answer:

Since it isn't really described in which way sides have been halved, I suppose that all 4 lengths have been halved and used to create a new square.

That square would be 1/4 of the old square.
