Can someone help me with this question? Please?

If the wwight of a package is multiplied by 7/10 the result is 65.8 find the weight of the package

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

Which point is a solution to y s 4x + 5?
