Answer:

D) -30x^2 -64x -18

Step-by-step explanation:

Given:

f(x) = 6x +2 and g(x) = -5x - 9

f(x).g(x) = (6x + 2) (-5x - 9)

Use distributive property

= 6x(-5x -9) + 2(-5x - 9)

= -30x^2 - 54x - 10x -18

= -30x^2 -64x - 18

Answer: d) -30x^2 -64x -18

Thank you.

What is the following product? 3√10(y^2√4 + √8y)
Elenna [48]

Answer:

6y^2√10 +12y √5

Step-by-step explanation:

3√10(y^2√4 + √8y)

Distribute

3√10(y^2√4) +3√10 (√8y)

3y^2 √40+3y√80

We know that √ab = √a√b

3y^2 √4*√10+3y√16√5

3y^2 *2*√10+3y*4√5

6y^2√10 +12y √5

The factorization of x2 + 3x – 4 is modeled with algebra
meriva

Option C: (x+4) and (x-1) are the factors of the equation

Explanation:

Given that the equation is x^{2} +3x-4

We need to determine the factors of the equation.

Splitting the middle term, we get,

x^{2} +4x-x-4

Grouping the terms, we have,

x(x+4)-1(x+4)

Let us factor out the term (x+4), we have,

(x+4)(x-1)

Thus, the factors of the equation are (x+4) and (x-1)

Hence, Option C is the correct answer.

In order to increase the circumference of a circle from 12π cm to 18π cm, by how much must the diameter increase?
Vadim26 [7]

Answer:


Step-by-step explanation:

It's actually 6 cm. This is because the diameter of the smaller circle is 12pi/pi which is 12, and the diameter of the bigger one is 18pi/pi which is 18. 12 + 6 = 18, so the diameter increases by 6.

17 + 5(x + 1)=37 <br> X= 15<br> X 3<br> X=-15<br> X=-3
aleksklad [387]

Answer:

X=3

Step-by-step explanation:

17 + 5(x + 1) = 37

17 + 5x + 5 = 37

Group like terms

5x = 37 - 17 - 5

5x = 15

\frac{5x}{5}  =  \frac{15}{5}

x = 3

4. Elena va a una fiesta pero no sabe que ponerse, así que lanza un moneda y un dado al
taurus [48]

Answer:

  • <u>1/4</u>

Explanation:

Hola. Puesto que tu pregunta está en español, te responderé en el mismo lenguage.

Estas son las posibilidades dadas por la combinación moneda/dado

                                      Número de combinaciones

Moneda: prenda

    Cara: vestido                 1 de 2:          1/2

     Sello: falda                    1 de 2:          1/2

Dado: color

    Par: negro                      3 de 6:          3/6

    Impar: café                     3 de 6:         3/6

En total son 2 × 6 resultados: 12 (incluye resultados repetidos, no son todos diferentes entre sí)

¿Cuántas combinaciones tienen vestido y color negro?

  • P(Vestido∩negro) = ?

Es decir: moneda = cara y dado = par

  • Son 1 × 3 = 3.

Por tanto, la probabilidad de vestido negro es:

  • 3 de 12 = 3/12 = 1/4 ← respuesta

Hay otras formas de resolverlo. Por ejemplo;

Como los resultados de lanzar la moneda y el dado son independientes:

  • P(Vestido∩negro) = P(Vestido) × P(Negro)
  • P(Vestido) = 1/2
  • P(Negro) = 3/6 = 1/2
  • P(Vestido) × P(Negro) = 1/2 × 1/2 = 1/4 ← mismo resultado
