Answer:

b

Step-by-step explanation:

Given

x³ + 5x² - 9x - 45 ( factor the first/second and third/fourth terms )

= x²(x + 5) - 9(x + 5) ← factor out (x + 5) from each term

= (x + 5)(x² - 9) ← factor as a difference of squares

= (x + 5)(x - 3)(x + 3)

Una fabrica produce 132 litros de yogurt diarios .Con 49 litros se llenan botellas de 0,25litros xada una y con el resto que que
Zina [86]

Answer:

z = 362\,botellas

Step-by-step explanation:

(This exercise has been presented in Spanish and for that reason explanation will be held in Spanish)

La cantidad de botellas de 0,25 litros que se llenan con 49 litros de yogurt es:

x = \frac{49\,L}{0.25\,\frac{L}{botella} }

x = 196\,botellas

La cantidad remanente de yogurt es:

V_{r} = 132\,litros - 49\,litros

V_{r} = 83\,litros

Ahora, la cantidad de botellas de 0,5 litros que se llenan con el volumen remanente es:

y = \frac{83\,litros}{0.5\,\frac{litros}{botella} }

y = 166\,botellas

Finalmente, el total de botellas a llenar es:

z = 196\,botellas + 166\,botellas

z = 362\,botellas

This one example of a net of a cube. how many more possible nets could there be of a cube
marshall27 [118]

Correct option is D) 10 .

<u>Step-by-step explanation:</u>

Net of a cube is : Basically , a cube consists of six square faces, twelve edges, and eight vertices. When the square faces of a cube are separated at the edges and laid out flat they make a two dimensional figure( 2D figure :- Comprises of x-axis & y-axis) called a net. There are eleven different nets for a cube.

  • Net -- a two-dimensional shape that can be folded into a three-dimensional figure is a net of that figure.
  • Face -- a plane figure that serves as one side of a solid figure.
  • Vertex -- the point at which two line segments, meet to form an angle.
  • Edge -- the line segment where two faces of a solid figure meet.

Since we have 11 nets of a cube ! According to question we have only one net given , that means there are 10 more net of a cub are left .Therefore , Correct option is D) 10 .

The cubic parent function is y = x³ , with no coefficients multiplied to x and with number added to or subtracted from x. Other cubic functions are a modified form of parent cubic function.

So, the answer is y = x³
