225 ft2

Mathematics
1 answer:

4 0

Answer:

12 ft

Step-by-step explanation:

we know the areas of the 2 top squares.

the area of a square is simply the square of its side length.

=>

81 ft² means side length is 9 ft.

225 ft² means side length is 15 ft.

these are also 2 of the sides of the right triangle.

the third side we get by using Pythagoras :

c² = a² + b²

with c being the side opposite of the 90 degree angle.

so,

225 = 81 + x²

as x is also the third side of the triangle.

=> 144 = x²

x = 12 ft

Averi estaba intentando factorizar 4x^2+20x-164x
Darina [25.2K]

Responder:

El ancho del modelo de área de Averi será x² + 5x-4

Explicación paso a paso:

Deje que el área del modelo de Averi sea igual a la ecuación dada

4x² + 20x-16

Si el mayor factor común del modelo es 4, esto significa que 4 se puede factorizar fácilmente de la ecuación como se muestra;

4 * (x² + 5x-4) ... (1)

Si la fórmula para el modelo de área = Largo * Ancho

Al comparar la fórmula para encontrar el área del modelo con la ecuación 1, el ancho del modelo de área será la función entre paréntesis, es decir,

x² + 5x-4

El ancho del modelo de área de Averi será x² + 5x-4

An airplane travels at 120 km/hr for 2 hours in a direction of 260° . At the end of this time, how far south.Of the airport is t
nadezda [96]

Answer:

the airplane is 130.56 km south of the airport after 2 hours

Step-by-step explanation:

given data

travel speed = 120

time travel = 2 hour

direction = 260°

solution

we get here direst distance covered by plane in 2 hours that is

distance cover = 120 × 2

distance cover = 240 kilometers

and

the south component of the distance will be here as

distance = 240 × sin(270 - 260) = - 130.56

so the airplane is 130.56 km south of the airport after 2 hours
