Answer:

7x^2 + 29xy -2y^2 + 8y

Step-by-step explanation:

3x(x+5y)+2y(7x-y)+4(x^2+2y)

Break all the brackets and you would hot:

= 3x*x + 3x*5y + 2y*7x - 2y*y + 4*x^2 + 4*2y

= 3x^2 + 15xy + 14xy -2y^2 + 4x^2 + 8y

= 3x^2 + 4x^2 +15xy + 14xy - 2y^2 + 8y

= 7x^2 + 29xy -2y^2 + 8y

Hope this help you :3
