Respuesta :

Step-by-step explanation:

a) (2x2+3y)+(y+2x-4)

(4+3y)+(y+2x-4)

4+3y+y+2x-4 this mean negative times positive is negative

4-4+3y+y+2x

0+4y+2x

4y+2x

I think this is the answer but I am not sure

B
Like terms have same variable with same power In 2x^2 +3y and 5y+3x^2 ,

2x^2 and 3x^2 are like terms and
3y and 5y are like terms
