The midpoint of AB is M(-2, -1). If the coordinates of A are (-7,2), what are the coordinates of B?

Factor the polynomial. b^2 + 4b + 4

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y

What is the value of x? enter your answer in the box. x =
