Answer: x= -7
Step-by-step explanation:
subtract 8x from both sides of the equation which would leave you with 2x+18=4
then you would subtract 18 from each side of the equation leaving you with 2x= -14
the divide by 2 on both sides of the equation giving you the answer of
x= -7
4 spinach with $1.00 left over

Answer:
1.2X = $
Step-by-step explanation:
Para construir una fórmula que permita calcular el dinero recaudado en un autobús en función de los billetes vendidos, sabiendo que cada uno cuesta 1,2 euros, se debe realizar el siguiente razonamiento lógico matemático:
1.2(variable fija) x X (número de billetes vendidos) = $ (Dinero recaudado)
1.2X = $
Por lo tanto, si por ejemplo se hubiesen vendido 100 billetes, la ecuación operaría de la siguiente manera:
1.2 x 100 = $
120 = $
(2x + 4) ( 2x + 3) = 4x² + 6x + 8x + 12 = 4x² +14x + 12
(4x + 5) (x + 1) = 4x² + 4x + 5x + 5 = 4x² + 9x + 5
(2x + 1) (2x + 5) = 4x² + 10x + 2x + 5 = 4x² + 12x + 5
Question one is (2x + 1) (2x + 5)
