There is actually not one set answer to 4x+7y, as what it means is 4 of one value plus 7 of another. The answer depends on what the values of x and y are, due to the equation meaning 4x+7y. For example, if x=2 and y=3, then the equation is 42+73=8+21=29. However, as I feel I have to note, these may not be the variables you'll get. I hope this helped!
It is the same. The equation "x + y" is the exact same as "x + y." There is no difference.
xy + x + y + 1 = (x + 1)(y + 1).
xz + x + yz + y = (x + y)(z + 1)
It is difficult to tell because this site uses a useless browser: one which cannot accept most mathematical symbols. So all we can see of the given equation is "y x2 10x plus 30", and the options appear as "y (x 5)2 plus 55 y (x 5)2 plus 30 y (x 5)2 5 y (x 5)2 plus 5".If the equation is y = x^2 - 10x + 30 then the answer is y = (x - 5) ^2 + 5.

(x + y)(x + y)(x + y)
The answer to Y x plus 5 Y 6 is Y(x+5Y5).One possible solution to y x plus 5 y 6 is Y(x+5Y5).
y += x means the value y+x is first calculated, and the resulting value is then assigned to y. It is equivalent to y = y+x

xy + x + y + 1 = (x + 1)(y + 1).
3xz+3yz+x+y=(x+y)(3z+1)
x + y + z = x + z + y is the commutative property of addition.
