Answer:
see explanation
Step-by-step explanation:
Note that 9x² and 49y² are perfect squares.
9x² = (3x)² → 3x is the first term
49y² = (7y)² → 7y is the second term
Hence
(3x + 7y)² = 9x² + 42xy + 49y²
Answer:
Precio de compra=$125.000
Ganancia= $25.000
Step-by-step explanation:
Dada la siguiente información:
Revalorización= 20%
Precio de venta= $150.000
<u>Para calcular el precio de compra, tenemos que usar la siguiente formula:</u>
Precio de compra= precio de venta / (1 + revalorización)
Precio de compra= 150.000 / (1,2)
Precio de compra=$125.000
Ganancia= 150.000 - 125.000
Ganancia= $25.000
0.3(3 - 0.5)
= 0.3(2.5)
= 0.75
