Answer:

number 3. is wrong you can reduce once more and it will equal 3/5. and number 4 would be 5/7.

Step-by-step explanation:

divide 12/20 by 2 on the top and bottom. you should get 6/10. you can divide that once more by 2 on the top and bottom and you should get 3/5. thats simplest form.

divide 25/35 by 5 on the top and bottom youll get 5/7. thats the simplest form.

hope this helped :)

On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction. The numb
Komok [63]

Option 1. The equation that represents the direct variation that exists between a and b is b = –a.

<h3>How to find the direct variation here</h3>

The direct variation is of this form y ∝ x

This gives the equation

y = kx

The constant is k

From our question we have

b ∝ a so b = ka

b = 2\frac{3}{4}

a = -2\frac{3}{4}

Remember that b = ka

2\frac{3}{4}  = -2\frac{3}{4} k

This would cancel out to

1 = -k

or k = -1

Hence the equation would be written as

b = -a

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
