Question

add x^2+y^2,y^2+z^2,2x+2y and 2y+2z​

Answer 1

Answer:

Step-by-step explanation:

Given that,

x² + y² , y² + z² , 2x+ 2y and 2y + 2z

Adding :

x² + y² + y² + z² + 2x + 2y + 2y + 2z

= x² + 2y² + z² + 2x + 4y + 2z is the answer.

Answer 2

Answer:

$x^{2} + 2y^{2} + z^{2} + 2x + 4y + 2z$

Step-by-step explanation:

[tex](x^{2} + y^{2}) + (y^{2} + z^{2}) + (2x + 2y) + (2y + 2z)\\ = x^{2} + y^{2} + y^{2} + z^{2} + 2x + 2y + 2y + 2z\\ = x^{2} + 2y^{2} + z^{2} + 2x + 4y + 2z[/tex]

Hope it helps...
