3xy-2xz+yz + 2xy-4xz-5yz

= (3xy + 2xy) + (-2xz - 4xz) + (yz - 5yz)

= 5xy - 6xz - 4yz

5x^2 + 3x - 2x^2 + 4x

= (5x^2 - 2x^2) + (3x + 4x)

= 3x^2 + 7x

To simplify the expression 12(x+4), you can distribute the 12 to both terms inside the parentheses:

12(x+4) = 12*x + 12*4 = 12x + 48

So the simplified form is 12x + 48.

To simplify the expression -2(2x-5), you can distribute the -2 to both terms inside the parentheses:

-2(2x-5) = -2*2x - 2*(-5) = -4x + 10

So the simplified form is -4x + 10.
