Write this trinomial in factored form 6y^2 - 17y + 5

Mathematics

Neporo4naja [7]4 years ago

Answer:

(3y - 1)(2y - 5)

Step-by-step explanation:

Given

6y² - 17y + 5

Consider the factors of the product of the coefficient of the y² term and the constant term which sum to give the coefficient of the y- term.

product = 6 × 5 = 30 and sum = - 17

The factors are - 2 and - 15

Use these factors to split the y- term

6y² - 2y - 15y + 5 ( factor first/second and third/fourth terms )

= 2y(3y - 1) - 5(3y - 1) ← factor out (3y - 1) from each term

= (3y - 1)(2y - 5) ← in factored form

Un equipo de futbol esta compuesto por 13 personas, contando el entrenador y el masajista. Tras jugar un partido, reciben para t
AleksandrR [38]

Answer:

Ok, tenemos que el cheque es de 16_41.

Y también sabemos que podemos dividir este numero entre 13 personas, de acá podemos concluir que este numero es un múltiplo de 13.

Sea el dígito faltan igual a x

Sabemos que un numero es divisible por 13 cuando la suma de los productos de las  unidades, decenas, centenas,...  De dicho número  por los dígitos contenidos en la lista {1, –3, –4, –1, 3, 4 } (en ese orden) es  0  o múltiplo de 13.

Entonces, tenemos:

16x41:

1*1 + 4*(-3) + x*-4 + 6*-1 + 1*3 = 1 - 12 -4x - 6 + 3

=-14 - 4*x  

entonces, -14 - 4*x tiene que ser igual a 0, 13 o algún múltiplo de 13.

Como ambos términos son negativos, no podemos tener esta igualdad igual a 0 o a 13, entonces apuntamos por el siguiente múltiplo de 13 después de -13 (es decir, 13*-2 = -26)

-26 = -14 - 4*x

-26 + 14 = -4*x

-12 = -4*x

-12/-4 = 3 = x

Entonces nuestro dígito es igual a 3, y nuestro numero es:

16341.

Ahora podemos probar:

16241/13 = 1257

Es decir, cada miembro recibe 1257.

Could anyone help me with this?
mario62 [17]

Answer:

x = 17

Step-by-step explanation:

Opposite Angles must be the Same Value so In other words, 2(8x - 5) + 2(4x - 19) = 360.

2(8x - 5) + 2(4x - 19) = 360

24x - 48 = 360

24x = 408

x = 17
