Answer:

(2a - \frac{y}{4} )(2a + \frac{y}{4} )

Step-by-step explanation:

4a² - \frac{y^2}{16} ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

4a² - \frac{y^2}{16}

= (2a)² - (\frac{y}{4} )²

= (2a - \frac{y}{4} )(2a + \frac{y}{4} )

If you have 30$ and you need to find 8%, and add to 30$ then find 15% of that, and what’s your total?
stira [4]

Answer:

Our total amount value is $4.86.

Step-by-step explanation:

The total amount given is $30.

Now  8 % of $30 = \frac{8}{100}  \times 30 = 2.4

or, 8% of $30  = $2.4

Now adding $30 and $2.4,

$ 30 + $2.4  = $32.4

Finding 15% of the total $32.4,

we get  \frac{15}{100} \times 32.4 = 4.86

or, 15% of $32.4   = $4.86

hence, our total amount value is $4.86.

tres hermanos danvueltas circuito en bicicleta. el mayor tarda 18 en dar Una vuelta el del medio 24 minutos yel menos 36 minutos
hodyreva [135]
Tienes que hallar el mínimo común múltiplo de las 3 cantidades.

18= 2×3²
24= 2³×3
36= 2²×3²

mcm(18,24,36) = 2³×3²=8×9= 72

Eso quier decir que si partieron a la misma hora se encontraran  de nuevo en el punto de partida 72 minutos después de la salida.

Las vueltas que habrán realizado será el resultado de dividir 72 entre el tiempo que tardan en dar una vuelta

<span>Mayor: </span>  = 4

<span>Mediano: </span>  = 3

<span>Pequeño: </span>  =  2

Soluciónes:

se vuelven a encontrar a los 72 min de la salida
<span>El mayor dió 4 vueltas, el mediano 3 y el pequeño 2</span>
