Angle1 and angle2 are supplementary angles. m angle1 find m angle2 . is 4y + 7 , and m angle2 is 9y + 4 .

3(10x-y)-5(x-y^2) need this solved asap

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares

If f(x) = 3x-2 and g(x) =2x+1 find (f-g)(x)
