2x ^ 2 + 5x + 2x + 5 = 2x ^ 2 + 3x - 8x - 12 + 5
7x - 8x - 3x = - 12 - 4x = - 12
x = 3.
12 - 15 - 20 2 6 15 10 2 3 15 5 3 1 5 5 5 1 1 1 2x2x3x5 = 60 el número es multiplo de 60 + 3 150 + 3 < 60 K + 3 < 200 + 3 2. 5 < k < 3. 3 k = 3 Entonces 60 k + 3 = 60 (3) + 3 = 183 Respuesta Gabriela tiene 183 cajitas.
