Answer:

\frac{x+7}{x-3}

Step-by-step explanation:

When you factor each equation, you result in two of the factors canceling out, resulting in \frac{x+7}{x-3}.

[Top Equation]

The middle number is 3 and the last number is -28.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 3

Multiply together to get -28

Can you think of the two numbers?

Try -4 and 7:

-4+7 = 3

-4*7 = -28

Fill in the blanks in

(x+_)(x+_)

with -4 and 7 to get...

(x-4)(x+7)

[Bottom Equation]

The middle number is -7 and the last number is 12.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -7

Multiply together to get 12

Can you think of the two numbers?

Try -3 and -4:

-3+-4 = -7

-3*-4 = 12

Fill in the blanks in

(x+_)(x+_)

with -3 and -4 to get...

(x-3)(x-4)

Solid A is dilated using a scale factor of 2⁄5, resulting in Solid B. Solid B is also dilated using a scale factor of 2⁄5, resul
Lyrx [107]

Answer:

28.8 and 180

Step-by-step explanation:

you just times B by 2/5 to get C and divide it by 2/5 to get A

C = (72)(2/5) = 28.8 km³

A = (72)/(2/5) = 180 km³

We know the answers make sense because A shrinks to get B and B shrinks to get C, and our answers match that.

Question 8 of 25<br> Which of the following is the quotient of the rational expressions shown here?
Alla [95]

Answer:

  B.  (5x+5)/(x²-2x)

Step-by-step explanation:

As with numerical fractions, division by a rational expression is equivalent to multiplication by its reciprocal.

<h3>As a multiplication problem</h3>

  \dfrac{5}{x-2}\div\dfrac{x}{x+1}=\dfrac{5}{x-2}\times\dfrac{x+1}{x}

<h3>Product of rational expressions</h3>

As with numerical fractions, the product is the product of numerators, divided by the product of denominators.

  =\dfrac{5(x+1)}{x(x-2)}=\boxed{\dfrac{5x+5}{x^2-2x}}
