Tres cuadrados iguales están superpuestos como indica la figura. Las áreas de las zonas superpuestas son de 2 cm2, 5 cm2 y 8 cm2, respectivamente. El área total de la zona no-superpuesta de los cuadrados es de 117 cm2. ¿Cual es la longitud del lado de cada cuadrado?

Use photo math it it’s so good

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
