Elena dice que las ecuaciones a y b no son equivalentes.
ecuación a: 13-5x 48 ecuación b: 5x = 35
escribe una explicación convincente de por qué esto es cierto.

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
