Step-by-step explanation:

add multiply divide subtract and add

Una expresión  es un grupo finito de términos algebraicos y símbolos matemáticos combinados en donde las letras se usan para representar números con valores desconocidos o imaginarios.

Una expresión consta de:

Coeficiente: que es el numero que no cambia o varia

Variable: representada por una letra y su valor cambia o fluctúa.

Para el enunciado, las variables son:

X= Nº de reproductores MP3

Y= Nº de reproductores DVD

Y las constantes son las ganancias por la venta de cada articulo

Ganancia de X = 35

Ganancia de Y= 15

La expresión que representa la ganancia por las ventas de MP3 y DVD, será:

G = 35X + 18Y

Step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
