I know that at least one of them is A but I’m not sure about the rest
El dinero que le falta a Maritza y su esposo para viajar es 330.
<h3>¿Cuánto dinero les falta?</h3>
Para calcular el dinero que les falta debemos identificar la cifra total que les va a costar el viaje:
- 750 + 800 + 180 + 750 + 650 = 3,130
El valor total del viaje es s/3,130, entonces les faltarían s/330.
3,130 - 2,800 = 330

Answer:
4 units
Step-by-step explanation:
according to question:
perimeter of square = 16 units
4a = 16
where a is the side length
a = 16/4
= 4 units
Sin(225)
225 degrees is in the 3rd quadrant. And in the third quadrant only tangent is positive, sin is negative.
For third quadrant, basic angle = 225 - 180 = 45
sin225 = - sin45
sin225 = - sin45 = -0.7071
sin 225° ≈ -0.7071
Answer:
49x²-16 = (7x - 4)(7x + 4)
Step-by-step explanation:
Your "49×2-16" is incorrect; did you mean "49x^2-16" or "49x²-16?"
This last expression is the difference of two squares.
The formula for that is a² - b² = (a - b)(a + b), and so your 49x²-16 factors as follows:
49x²-16 = (7x - 4)(7x + 4)
