the correct answer would be D
Answer:


Step-by-step explanation:
Recall that an expression that can be factored as (U+V)(U-V) using distributive property for multiplication of binomials, should render:
(the factorization given above is that of a difference of squares. Then, the idea is to write the original expression :

as a difference of perfect squares. Let's examine each term and its numerical and variable form to find if they can be written as perfect squares:
a) the term
therefore, if we assign the letter U to
, the first term becomes:

b) the term
therefore, if we assign the letter V to
, this second term becomes:

With the above identification, our expression can now be factored as a difference of squares:

Answer:
2.3 (or 2.293)
Step-by-step explanation:
25/10.99
Complete question :
si para introducir un producto al país se pagan $225 por concepto de impuestos y dicho producto cuesta $1,200 ¿que porcentaje se cobra por impuesto?
Responder:
18,75%
Explicación paso a paso:
Dado que:
Monto cobrado por impuestos = $ 225
Costo del producto sujeto a impuestos = $ 1200
El porcentaje del precio de costo del producto que se grava:
Sea porcentaje = x%
x% * precio de coste = importe de impuestos
0.01x * $ 1200 = $ 225
12x = 225
x = 225/12
x = 18,75
Por tanto, porcentaje de impuesto = 18,75%
